By calling this method applications provide a thread to the EventDispatcher for it to use to dispatch events. This call will not return until the EventDispatcher stops dispatching events. The application can call this method multiple times for the same instance of an EventDispatcher to provide a pool of threads.

dispatcherThread() can be called at any time either before or after start() has been called on the EventDispatcher but events will only be dispatched after start() has been called.
