This sounds like a messy decision. Is this single-mutex stuff in pf true for OpenBSD as of now or a port quirk of FreeBSD's version? I worked on a heavily multi-threaded firewall core for a few years and I would be glad to help pf itself instead of a 4.5-based pf port going SMP, chasing rainbows and unicorns. Franco
