You don't have to necessarily use kqueue on a BSD. In areas where it might make more sense performance wise you can obviously use poll. I'm not opposed to introducing an alternative interface like epoll, but it's only recently that Linux has managed to bridge the network performance gap. I attribute that to a lot of money being poured into it with pure and raw optimization from all of the Linux sponsors that they get which is really cool and great for them but it does not necessarily make gnu/Linux a purer system. Both approaches have their merits. There's no reason to sit here and claim that one is better than the other
