This has nothing to do with the bug.  The bug has to do with post mortium
finalization not happening.  This is not happing due to the fact egtp is
inbetween two ways of doing PMF: <obj>.shutdown() and
<obj>.extres.__del__().

I've fixed mesgen.py so that it's PMF is called, that was the complex one
that used bsddb3.  Now I'm trying to fix the ones that use LazySaver as base
class.  LazySaver uses pickles.

The current MAIN branch will pop a wxPython window showing all refs to
TCPCommsHandler.  You can run this and see what I'm trying to get to
shutdown.

egtp.ListenerManager.ListenerManager
egtp.TCPCommsHandler.TCPCommsHandler
egtp.ListenerManager.ListenerManager

Are all hanging around and not doing their LazySaver.__del__ stuff.
