You may wish to consider a more orderly shutdown (send the server a
signal upon which it shuts itself down), but the simplest and most
direct solution is to set the SO_REUSEADDR flag.

http://docs.python.org/library/socket.html?highlight=so_reuseaddr

I've not actually used the TCPServer class myself, but a cursory
glance at the docs suggests that it's possible if you subclass it:
