-/**
- * 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.
- * Each has a name. You ask LLCoros to launch a new coroutine with a suggested
- * name prefix; from your prefix it generates a distinct name, registers the
- * new coroutine and returns the actual name.
- *
- * 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
- * currently-running coroutine.
- *
- * Finally, the next frame ("mainloop" event) after the coroutine terminates,
- * LLCoros will notice its demise and destroy it.

- * This class helps the implementer of a given event API to honor the

- * response LLSD a ["reqid"] key whose value echoes the ["reqid"] value, if
- * any, from the corresponding request.
- *
- * This supports an (atypical, but occasionally necessary) use case in which
- * two or more asynchronous requests are multiplexed onto the same ["reply"]
- * 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
- * that case. Though LLSD::UUID is guaranteed to work, it might be overkill:
- * 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
- * LLReqID?" and look up this material.
- *
- * The hardest part about the convention is deciding where to store the
- * ["reqid"] value. Ironically, LLReqID can't help with that: you must store
- * an LLReqID instance in whatever storage will persist until the reply is
- * sent. For example, if the request ultimately ends up using a Responder
- * subclass, storing an LLReqID instance in the Responder works.
- *
- * @note
- * The @em implementer of an event API must honor the ["reqid"] convention.
- * 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
- * LLEventStream and pass its name to the event API in question. Then it's
- * perfectly reasonable not to set a ["reqid"] key in the request, ignoring

- *
- * Now we publish only the single canonical listen() method, so there's a

- * To support automatic connection management, we use boost::visit_each

- * Cases:
- * * At least one of the function's arguments is a boost::weak_ptr<T>. Pass

- * 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

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.
