You're going to want to look at the threading module for threads, and
the socket and the select modules for networking. threading.Event and
threading.Timer may be of interest as to communicating with the other
thread and setting a timeout.

This isn't actually as trivial a problem as it may sound on the surface,
by the way, so don't worry if it takes a while to get right!
