* FireQueueEmpty now checks if a measurable amount of time has passed, and if not it sleeps for a small amount of time. This throttles OnQueueEmpty calls where there is no callback or the callback is doing very little work 

* Changed HandleQueueEmpty()'s Monitor.TryEnter() calls to locks. We want to take our time in this function and do all the work necessary, since returning too fast will induce a sleep anyways
