332 Yet another way of getting messages into Command. This one is for events that
333 are not standard button presses (or UDP generated buttons). It is also not for
334 events that are generated as a result of other events (events that can safely
335 call postMessageNoLock and be guaranteed that the message will be processed
336 because it is known that the queue is currently being processed).
337 This is for events that come from outer space and can occur when the master
338 mutex is locked or not, they need to be queued and executed but it doesn't
340 Actually so far it is for events caused by the video stream - aspect ratio
341 changes. These can occur when the master mutex is locked and so postMessage
342 doesn't work. postMessageNoLock doesn't work because if the mutex *isn't*
343 locked at the time then the message could be sat around a while before
345 The whole message system was at first supposed to prevent the problem of
346 calling a function on an object that had just been deleted, by ordering
347 messages such that all calls are done before object deletion. However,
348 because of the new centralised messaging system and the fact that BoxStack
349 locates the destination object before calling it, the messaging system now
350 allows the kind of sloppy calls it was supposed to stop. Weird huh. This
351 is mentioned here because the video stream might generate an event just as
352 the user hits stop. The mutex is locked, and by the time the message
353 is examined the vvideorec/live has been deleted. This doesn't matter because
354 boxstack will drop the message if it can't find the matching object to
356 Finally, all this is fine and dandy, except that I'm not 100% sure that
357 this sloppy postMessage and hope a queued signal will force it to be processed
358 thingy will actually work. Hmmm.
359 Lastly <g>, I will consider making the naming system a little more sane

454 Instead of sending through the boxstack, implement a more generic MessageReceiver interface
455 and have potential receivers register with something
