Possibly related to this is that if I delete my pkgsrc tree and 'cvs
up' it again I use up about 250 mbufs according to netstat -m.  If I
immediately run 'cvs up' again on the freshly updated tree I start to
see my mbufs climb quite quickly.  Which I believe lead to this error
output before my laptop crashed.
