Surprising `netstat -m' output

[YONETANI Tomokazu <qhwt+dfly@xxxxxxxxxx>]

Hello.
I'm seeing strange numbers from `netstat -m' on recent -CURRENT:

$ cd /usr/src && cvs up -dP	(to pull the source from local pserver)
$ netstat -m
258/2/13312 mbufs in use (current/peak/max):
        258 mbufs allocated to data
4294966501/4294966501/6656 mbuf clusters in use (current/peak/max)
4192714 Kbytes allocated to network (242% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines

I can reproduce this on kernels built today and on 16th. The numbers
from `vmstat -m' don't look unusual, so maybe it's not really an mbuf
leak?

Regards.
