* Bounded queues for the EventHandler thread (#58)

* Bounded queue for the EventHandler thread

The unbounded queue fronting the 'event' thread can cause trouble when the
EventHandler is unable to keep up with the workload. This can lead to heap
exhaustion, GC issues and failure modes that are generally considered "bad".

Band-aid over this with a semaphore to limit the number of tasks in the queue.
The semaphore is opt-in and disabled by default to avoid any nasty surprises
for folks upgrading.

Also add 'EventSource.awaitClosed()' to allow users to wait for underlying
thread pools to completely shut down. We can't know if it's safe to clean
up resources used by the EventHandler thread if we can't be certain that it
has completely terminated.

* Address checkstyle griping in StubServer

* Fix JavaDoc issue

* Tighten up exception handling
