OK, just had another incident.

Under normal operations of this machine, I have about 530-540 mbufs in 
use (as reported by netstat -m).  When it "hung", I had 899 in use, and 
a "ping" to a local neighbor reported "no buffer space available".

Interestingly, "vmstat -m" reported zero failures.

BTW, what are "calls to protocol drain routine"?  These seem to go up 
very slowly over time, and there were 18 at the time of the failure.

I tried again to "ifconfig wm0 down" and the process hung.  I tried to 
switch back to another xterm session, and it was unable to re-draw the 
window.
