I orginally replied to Dave off-list, but I saw a couple of hangups on 
our 6.3/amd64/SMP/4BSD master during/after some NSCA result submission 
bombs caused by some wide outages.  There was really no impact in terms 
of resource consumption or race conditions, just unresponsive daemons 
(the debug log just kept cycling through the "nothing to do!" routine.)

I wasn't too worried about it since it was caused by extremely atypical 
events so I didn't do much troubleshooting, but I can at least confirm 
the behavior.
