(Sounds like a huge security risk, unless you have tight control over 
who can connect to that socket.)

The issue isn't killing a thread in Python, it's killing the *new 
process* which that thread has started.  To do that you have to rely on 
OS-specific (i.e. non-portable) techniques.  Googling for "python kill 
process" would probably get you off to a good start.
