Dispatching a Win32 COM in the background?

[David LeBlanc]

Hmmm... and the run method of Background could be sitting on one end of a
Queue (Queue is thread-safe: see your python doc for details) that's
buffering the asyncronous calls on the speacher. The main task then just
stuffs a talk request into the queue and the Background processes it when it
gets to it.
