Even more offtopic - on Linux I saw there's a kernel thread for each 
interface. Interestingly, while routing 1 Gbps of traffic through the 
system (just a single download of a huge file over HTTP), on Linux 
kernel 2.6.18 both kernel threads are at 35% CPU usage, while on OpenBSD 
4.1 the single kernel thread is at 70...80%. Maybe a coincidence, maybe 
the numbers don't usually translate linearly like that, I don't know.

I like pf, it's a really clever firewall, that's why I'll keep testing 
with 4.2
