This is just a wild-ass guess, but in Dibbler.run(), it seems that something
like:

    while True:
        try:
            asyncore.loop(map=context._map)
        except socket.error, arg:
            if arg[0][0] == 110:
                # socket timeout
                print >> sys.stderr, "timeout"
                continue
            else:
                raise

might give you the ability to recover from timeouts.  This is of course
subject to whatever asyncore might do under the covers, and there's no
guarantee the test in my if stmt is correct (or if "correct", also robust).
