If you can get the pid of the process you created, you should be able
to use the killProcName function that's included with the win32
package...if you're server is a Windows box. You should be able to use
the join() method if you don't set your thread to a Daemon.

This post talks about using the os module to kill a thread as well:

The wxPython wiki has one of the best threading examples I've seen:
