So, logically, one would conlude that your thread never exits, even when
you disconnect.  You'd better post code, or start sticking print statements
inside until you discover what is actually happening in your code.

Or replace the thread target with a function that does a simple time.sleep()
and observe the results.  You should see the process exit, which ought to
prove to you that the problem is with your specific server code, and not
threads in Python.
