On the second part, I stand by my previous statements that threads or processes should be used sparingly. All I'm doing is trying to counter all the "threads are great" hype. This is a pretty intelligent pile of people but there are also a fair number of people who read this list looking for nuggets of information. If they walk away going "(a) Linux has a cool threading model, and (b) I should only use threads if I absolutely have to do so and even then if there are more than there are CPUs I'm probably making a mistake", if they get that message, that's a good thing, IMHO. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm
