Well, hmm.

Given the length of time the problem's been around I'm shifting toward the idea
that it's a matter of nmap's standards compliance more so than a fault in the 
BSD
network stack.

I have noticed a workaround though.. if a slight delay is introduced to the 
scan,
it will continue without incident, a la..

nmap --scan_delay 1 -sS -vvv <hostname>

Where 1 is a time in milliseconds.
