The only way to "kill" a thread is to have the spawned thread have
some kind of passed in argument which will trigger it to shut down.
You could have the thread read a file or file-like object periodically
(like a timer) and if it meets some condition, have the thread quit.
It's kind of like a subscription process. The thread subscribes to the
main program and can accept signals. I suggest that the OP read the
docs on threads:
http://docs.python.org/lib/module-thre...
Of special interest to this user:
http://docs.python.org/lib/condition-ob...
I have messed with KillProcName, a PyWin32 script with limited
success. There's also the following snippet which is Windows only and
works for some processes and not others (i.e. unreliable):
subprocess.Popen('taskkill /s %s /im %s' % (computer_id, proc))
Hopefully I didn't muddy the waters or write something too off the
mark.
