This probably is the trickest part, not difficult for non-fastforward case. But if fastforward is enabled, I could only imagine full cross-cpu states duplication.

FWIW, there is decreasing difference between IP fast forwarding and regular IP processing in FreeBSD 7.x, as we perform direct dispatch by default, so it's not just the fast forward case where full input parallelism is possible for the firewall, and parallel firewall processing has occurred for output since 5.3.
