+/**
+ * Registry of named Boost.Coroutine instances
+ *
+ * The Boost.Coroutine library supports the general case of a coroutine
+ * accepting arbitrary parameters and yielding multiple (sets of) results. For
+ * such use cases, it's natural for the invoking code to retain the coroutine
+ * instance: the consumer repeatedly calls into the coroutine, perhaps passing
+ * new parameter values, prompting it to yield its next result.
+ *
+ * Our typical coroutine usage is different, though. For us, coroutines
+ * provide an alternative to the @c Responder pattern. Our typical coroutine
+ * has @c void return, invoked in fire-and-forget mode: the handler for some
+ * user gesture launches the coroutine and promptly returns to the main loop.
+ * The coroutine initiates some action that will take multiple frames (e.g. a
+ * capability request), waits for its result, processes it and silently steals
+ * away.
+ *
+ * This usage poses two (related) problems:
+ *
+ * # Who should own the coroutine instance? If it's simply local to the
+ * handler code that launches it, return from the handler will destroy the
+ * coroutine object, terminating the coroutine.
+ * # Once the coroutine terminates, in whatever way, who's responsible for
+ * cleaning up the coroutine object?
+ *
+ * LLCoros is a Singleton collection of currently-active coroutine instances.

+ * name prefix; from your prefix it generates a distinct name, registers the

+ *
+ * The name can be used to kill off the coroutine prematurely, if needed. It
+ * can also provide diagnostic info: we can look up the name of the

+ *
+ * Finally, the next frame ("mainloop" event) after the coroutine terminates,

+ *
+ * This supports an (atypical, but occasionally necessary) use case in which

+ * LLEventPump. Since the response events could arrive in arbitrary order, the
+ * caller must be able to demux them. It does so by matching the ["reqid"]
+ * value in each response with the ["reqid"] value in the corresponding
+ * request.
+ *
+ * It is the caller's responsibility to ensure distinct ["reqid"] values for

+ * the "namespace" of unique ["reqid"] values is simply the set of requests
+ * specifying the same ["reply"] LLEventPump name.
+ *
+ * Making a given event API echo the request's ["reqid"] into the response is
+ * nearly trivial. This helper is mostly for mnemonic purposes, to serve as a
+ * place to put these comments. We hope that each time a coder implements a
+ * new event API based on some existing one, s/he will say, "Huh, what's an

+ *
+ * The hardest part about the convention is deciding where to store the

+ * an LLReqID instance in whatever storage will persist until the reply is
+ * sent. For example, if the request ultimately ends up using a Responder

+ * @note

+ * However, the @em caller of an event API need only use it if s/he is sharing
+ * the same ["reply"] LLEventPump for two or more asynchronous event API
+ * requests.
+ *
+ * In most cases, it's far easier for the caller to instantiate a local

+/**
+ * We originally provided a suite of overloaded

+ * LLEventTrackable::track(). This was workable but error-prone: the coder
+ * must remember to call listenTo() rather than the more straightforward
+ * listen() method.
+ *
+ * Now we publish only the single canonical listen() method, so there's a
+ * uniform mechanism. Having a single way to do this is good, in that there's
+ * no question in the coder's mind which of several alternatives to choose.
+ *
+ * To support automatic connection management, we use boost::visit_each
+ * (http://www.boost.org/doc/libs/1_37_0/doc/html/boost/visit_each.html) to
+ * inspect each argument of a boost::bind expression. (Although the visit_each
+ * mechanism was first introduced with the original Boost.Signals library, it
+ * was only later documented.)
+ *
+ * Cases:
+ * * At least one of the function's arguments is a boost::weak_ptr<T>. Pass
+ * the corresponding shared_ptr to slot_type::track(). Ideally that would be
+ * the object whose method we want to call, but in fact we do the same for
+ * any weak_ptr we might find among the bound arguments. If we're passing
+ * our bound method a weak_ptr to some object, wouldn't the destruction of
+ * that object invalidate the call? So we disconnect automatically when any
+ * such object is destroyed. This is the mechanism preferred by boost::
+ * signals2.
+ * * One of the functions's arguments is a boost::shared_ptr<T>. This produces
+ * a compile error: the bound copy of the shared_ptr stored in the
+ * boost_bind object stored in the signal object would make the referenced
+ * T object immortal. We provide a weaken() function. Pass
+ * weaken(your_shared_ptr) instead. (We can inspect, but not modify, the
+ * boost::bind object. Otherwise we'd replace the shared_ptr with weak_ptr
+ * implicitly and just proceed.)
+ * * One of the function's arguments is a plain pointer/reference to an object
+ * derived from boost::enable_shared_from_this. We assume that this object
+ * is managed using boost::shared_ptr, so we implicitly extract a shared_ptr
+ * and track that. (UNDER CONSTRUCTION)
+ * * One of the function's arguments is derived from LLEventTrackable. Pass
+ * the LLBoundListener to its LLEventTrackable::track(). This is vulnerable
+ * to a couple different race conditions, as described in LLEventTrackable
+ * documentation. (NOTE: Now that LLEventTrackable is a typedef for
+ * boost::signals2::trackable, the Signals2 library handles this itself, so
+ * our visitor needs no special logic for this case.)
+ * * Any other argument type is irrelevant to automatic connection management.
