The TCPServer class does not use threading.  But the subclass
ThreadingTCPServer does.  There is also a ForkingTCPServer and
ThreadingUDPServer.   They are all used the same way.

You have a handler class to process a request.  Create a subclass
and override the "handle" method.  Then pass the subclass to the
Server class.

>>> from SocketServer import ThreadingTCPServer, StreamRequestHandler
>>> class EchoStreamRequestHandler(StreamRequestHandler):
...   def handler(self):
...     line = self.rfile.readline()  # get info from client
...     self.wfile.write(line)        # write it back to client
...
>>> server_address = ('', 9999)  # dummy hostname and socket to listen on
>>> server = ThreadingTCPServer( server_address, EchoStreamRequestHandler )
>>> server.serve_forever()            # start up the server

You might want to look at the BaseHTTPServer.py to see how the SocketServer
module is used in other ways.
