You should probably check out this thread:

http://groups.google.com/group/comp.lang.python/browse_thread/thread/4ac31cd3a389a4d8/

And this might help as well:

http://www.pyzine.com/Issue001/Section_Articles/article_ThreadingGlobalInterpreter.html

And here's a wxPython specific article on threading:

http://wiki.wxpython.org/LongRunningTasks

You might consider posting to the wxPython mailing list too, as they
can probably help you more.
