Based on what you guys have said i've had a look at the code for 
serve_forever() in both 2.5 and 2.6, and tried to create my own derived 
class in this manner:

class MBThreadingTCPServer(SocketServer.ThreadingTCPServer):

    def __init__(self, address_tuple, handler):
        SocketServer.ThreadingTCPServer.__init__(self, address_tuple, handler)
        self.__serving = True

    def serve_forever(self):
        while self.__serving:
            SocketServer.ThreadingTCPServer.handle_request(self)

    def shutdown(self):
        self.__serving = False

Don't worry about the MB thing, it's just related to the name of our project.

I don't think i've done this right, but i've tried to implement the 
serve_forever() functionality in my derived class, and also add the 
shutdown() method so i can stop it.

Does this appear to be the right way to do things?

Cheers,

Dave
