Yes.  I'm running it a thread.  It's tough to debug because the code
is wrapped up as an exe.  ie. There is no local python install to test

Can you elaborate on what WSANOTINITIALZED actually means?  Where is
it called in the Python code?  Inside socket.py?  Can I force a
WSASTARTUP call in python code?

PS. Im on Windows. Thanks!
