Assuming this is really a problem, could CARP use interface link state

to speed up fail-over?  E.g., if the common setup is two routers with

a direct Ethernet cable for pfsync and the common failure scenario is

power failure (or at least something that brings down the pfsync

device interface), when one router fails, the other could detect the

link state change and then try to more aggressively contact the master

before timing out and taking over.
