Hmm. Lonely topic ;-)

I've found a way to solve the problem, by creating a subclass of
HTTPServer which overrides the handle_error method:

class HelpServer(HTTPServer):
    def handle_error(self, request, client_address):
        exception_line = inspect.trace()[-1][-2][0]
        if "sys.exit" in exception_line:
            print "Trying to exit again!"
            HTTPServer.handle_error(self, request, client_address)

This seems a really nasty hack though - any ideas for a cleaner way to
do it?
