It wouldn't have those side-effects if push really just pushed. :-P > We do not live in a pure world, Python isn't pure (practicality beats > purity), and by attempting to send some data each time a .push*() > method is called, there are measurable increases in transfer rates. -- 8< -- > Yes, it would be convenient to not have push*() actually send data > when called in some cases, but in others, the increase in data > transfer rates and/or reduction in latency is substantial. If it increases transfer speed that much, the calling application almost has to be broken, or at least not designed as it should be - of course there are such applications, but you know... Anyway, I went for a subclassing way of dealing with it, and it works fine. Thanks for the reply though, hadn't considered possibly "flawed" applications where the asyncore loop isn't revisited as often as it should. :-> Ludvig -- http://mail.python.org/mailman/listinfo/python-list
