 I narrowed this bug down to the following patch to djb's ucspi-tcp
 (adds ipv6 functionality):
 http://www.fefe.de/ucspi/
 
 I don't think that userland processes should be able to wreak that
 much havoc on the network stack.  Another thing of note is that even
 if I kill the processes causing the problem, the mbufs are never
 reclaimed.  Seems like a permanent leak.
 
 When I got rid of the ipv6 patch, the mbufs stopped building up and
 everything has been fine..  Note that the ipv6 traffic for this
 process was fairly minimal.
