Multi-platform Threading

[Lane LiaBraaten]

I am working on an app that uses the threading module and Queue.Queue(s) for 
communicating between the threads.  Everything was working on Linux (Redhat 
7.3) but when I tried it on WinNT 4.0 it hung at random times during thread 
execution.

Sometimes I get this error and the program craches:
---------------------------------------
TclExecuteByteCode: done instruction at pc 45: stack top 19 != entry stack top 
-1
TclExecuteByteCode execution failure: end stack top != start stack top

abnormal program termination
---------------------------------------

Most of the time the program can start a new thread, but the thread never 
finishes what it is doing and the program hangs.
