+		 * - "" (default): let the child inherit the same file handle used by
+		 *   this process. For instance, if passed as stdout, child stdout
+		 *   will be interleaved with stdout from this process. In this case,
+		 *   @a name is moot and should be left "".
+		 *
+		 * - "file": open an OS filesystem file with the specified @a name.
+		 *   <i>Not yet implemented.</i>
+		 *
+		 * - "pipe" or "tpipe" or "npipe": depends on @a name
+		 *
+		 *   - @a name.empty(): construct an OS pipe used only for this slot
+		 *     of the forthcoming child process.
+		 *
+		 *   - ! @a name.empty(): in a global registry, find or create (using
+		 *     the specified @a name) an OS pipe. The point of the (purely
+		 *     internal) @a name is that passing the same @a name in more than
+		 *     one slot for a given LLProcess -- or for slots in different
+		 *     LLProcess instances -- means the same pipe. For example, you
+		 *     might pass the same @a name value as both stdout and stderr to
+		 *     make the child process produce both on the same actual pipe. Or
+		 *     you might pass the same @a name as the stdout for one LLProcess
+		 *     and the stdin for another to connect the two child processes.
+		 *     Use LLProcess::getPipeName() to generate a unique name
+		 *     guaranteed not to already exist in the registry. <i>Not yet
+		 *     implemented.</i>
+		 *
+		 *   The difference between "pipe", "tpipe" and "npipe" is as follows.
+		 *
+		 *   - "pipe": direct LLProcess to monitor the parent end of the pipe,
+		 *     pumping nonblocking I/O every frame. The expectation (at least
+		 *     for stdout or stderr) is that the caller will listen for
+		 *     incoming data and consume it as it arrives. It's important not
+		 *     to neglect such a pipe, because it's buffered in memory. If you
+		 *     suspect the child may produce a great volume of output between
+		 *     frames, consider directing the child to write to a filesystem
+		 *     file instead, then read the file later.
+		 *
+		 *   - "tpipe": do not engage LLProcess machinery to monitor the
+		 *     parent end of the pipe. A "tpipe" is used only to connect
+		 *     different child processes. As such, it makes little sense to
+		 *     pass an empty @a name. <i>Not yet implemented.</i>
+		 *
+		 *   - "npipe": like "tpipe", but use an OS named pipe with a
+		 *     generated name. Note that @a name is the @em internal name of
+		 *     the pipe in our global registry -- it doesn't necessarily have
+		 *     anything to do with the pipe's name in the OS filesystem. Use
+		 *     LLProcess::getPipeName() to obtain the named pipe's OS
+		 *     filesystem name, e.g. to pass it as the @a name to another
+		 *     LLProcess instance using @a type "file". This supports usage
+		 *     like bash's &lt;(subcommand...) or &gt;(subcommand...)
+		 *     constructs. <i>Not yet implemented.</i>
+		 *
+		 * In all cases the open mode (read, write) is determined by the child
+		 * slot you're filling. Child stdin means select the "read" end of a
+		 * pipe, or open a filesystem file for reading; child stdout or stderr
+		 * means select the "write" end of a pipe, or open a filesystem file
+		 * for writing.
+		 *
+		 * Confusion such as passing the same pipe as the stdin of two
+		 * processes (rather than stdout for one and stdin for the other) is
+		 * explicitly permitted: it's up to the caller to construct meaningful
+		 * LLProcess pipe graphs.

+/**
+ * This class is a growable buffer between a producer and consumer. It serves
+ * as a queue usable with Boost.Iostreams -- hence, a "stream queue."
+ *
+ * This is especially useful for buffering nonblocking I/O. For instance, we
+ * want application logic to be able to serialize LLSD to a std::ostream. We
+ * may write more data than the destination pipe can handle all at once, but
+ * it's imperative NOT to block the application-level serialization call. So
+ * we buffer it instead. Successive frames can try nonblocking writes to the
+ * destination pipe until all buffered data has been sent.
+ *
+ * Similarly, we want application logic be able to deserialize LLSD from a
+ * std::istream. Again, we must not block that deserialize call waiting for
+ * more data to arrive from the input pipe! Instead we build up a buffer over
+ * a number of frames, using successive nonblocking reads, until we have
+ * "enough" data to be able to present it through a std::istream.
+ *
+ * @note The use cases for this class overlap somewhat with those for the
+ * LLIOPipe/LLPumpIO hierarchies, and indeed we considered using those. This
+ * class has two virtues over the older machinery:
+ *
+ * # It's vastly simpler -- way fewer concepts. It's not clear to me whether
+ *   there were ever LLIOPipe/etc. use cases that demanded all the fanciness
+ *   rolled in, or whether they were simply overdesigned. In any case, no
+ *   remaining Lindens will admit to familiarity with those classes -- and
+ *   they're sufficiently obtuse that it would take considerable learning
+ *   curve to figure out how to use them properly. The bottom line is that
+ *   current management is not keen on any more engineers climbing that curve.
+ * # This class is designed around available components such as std::string,
+ *   std::list, Boost.Iostreams. There's less proprietary code.

+ * LLTypeInfoLookup is specifically designed for use cases for which you might
+ * consider std::map<std::type_info*, VALUE>. We have several such data
+ * structures in the viewer. The trouble with them is that at least on Linux,
+ * you can't rely on always getting the same std::type_info* for a given type:
+ * different load modules will produce different std::type_info*.
+ * LLTypeInfoLookup contains a workaround to address this issue.
+ *
+ * Specifically, when we don't find the passed std::type_info*,
+ * LLTypeInfoLookup performs a linear search over registered entries to
+ * compare name() strings. Presuming that this succeeds, we cache the new
+ * (previously unrecognized) std::type_info* to speed future lookups.
+ *
+ * This worst-case fallback search (linear search with string comparison)
+ * should only happen the first time we look up a given type from a particular
+ * load module other than the one from which we initially registered types.
+ * (However, a lookup which wouldn't succeed anyway will always have
+ * worst-case performance.) This class is probably best used with less than a
+ * few dozen different types.

+ * Idiom useful for test programs: catch an expected exception, store its
+ * what() string in a specified std::string variable. From there the caller
+ * can do things like:
+ * @code
+ * ensure("expected exception not thrown", ! string.empty());
+ * @endcode
+ * or
+ * @code
+ * ensure_contains("exception doesn't mention blah", string, "blah");
+ * @endcode
+ * etc.
+ *
+ * The trouble is that when linking to a dynamic libllcommon.so on Linux, we
+ * generally fail to catch the specific exception. Oddly, we can catch it as
+ * std::runtime_error and validate its typeid().name(), so we do -- but that's
+ * a lot of boilerplate per test. Encapsulate with this macro. Usage:
+ *
+ * @code
+ * std::string threw;
+ * try
+ * {
+ *     some_call_that_should_throw_Foo();
+ * }
+ * CATCH_AND_STORE_WHAT_IN(threw, Foo)
+ * ensure("some_call_that_should_throw_Foo() didn't throw", ! threw.empty());
