     wxMessageQueue allows passing messages between threads.
 
     This class should be typically used to communicate between the main and worker
     threads. The main thread calls wxMessageQueue::Post and the worker thread
     calls wxMessageQueue::Receive.
 
-    For this class a message is an object of arbitrary type T.

     Notice that often there is a some special message indicating that the thread
     should terminate as there is no other way to gracefully shutdown a thread
     waiting on the message queue.
