It sounds like using 'defer' may allow pf + pfsync to handle the issues
resulting from asymmetric routing of packets, as long as the asymmetry
is fully contained within the pfsync'd hosts.

I apologize if I gave too much airtime to the pf + pfsync aspects of
what I was trying to resolve, we largely worked around those by enabling
carp preemption.
