The SocketServer docs say:
"The solution is to create a separate process or thread to handle each request; the 
ForkingMixIn and ThreadingMixIn mix-in classes can be used to support asynchronous 
behaviour. "

And if you look in SocketServer.py (from python 2.3.3) you'll see at line 479:

class ForkingUDPServer(ForkingMixIn, UDPServer): pass
class ForkingTCPServer(ForkingMixIn, TCPServer): pass

class ThreadingUDPServer(ThreadingMixIn, UDPServer): pass
class ThreadingTCPServer(ThreadingMixIn, TCPServer): pass


So it already defines 4 specialized server classes for you to use :-)
Threading, or forking, whatever suits you best.
If you want a TCP server that uses a new thread for each request,
just use SocketServer.ThreadingTCPServer instead of
SocketServer.TCPServer and you're done!
