I agree wholeheartedly. The coupling of the ARP code to the forwarding 
code in the BSDs has been largely historical. Other implementations have 
done this, and it generally simplifies the layer 3 forwarding code.

If done carefully, the performance impact should be minimal. rwlocks 
might be the way to go here.

In my opinion this kind of change has been needed for a long time, sadly 
I can't offer any resources to help move this along just now.
