You can argue this, but then we are left with software that will only run well on AIX or [insert pet platform here], and runs dog slow on other platforms, because it assumes that the underlying implementation will always be O(log2(N)) instead of O(N) or O(N**2). It's a really crappy program that relies on underlying OS specific features for its efficiencies, because as soon as it's ported to an OS where the assumptions it makes are no longer true, it's screwed. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
