If you have a look at the medusa/thread/select_trigger.py file (get the
CVS one if possible as the release isn't very up to date) at:

http://sourceforge.net/projects/oedipus/

You will see another way of doing it.  This uses a trick where the
code internally sets up a pair of connected sockets.  You can then 
wake up (trigger) the thread with the asyncore.loop in it by writing
to the one of the connected sockets.
