I don't need to lock the per-CPU locks to merely read the stats
(unless I'm reall obsessed with getting consistent stats at the cost of
performance every time a person issues `netstat -m' or, even worse, runs
`systat -mbufs'). The main issue with the mbtypes stats, as I've previously
mentionned, was that it is difficult to *update* them consistently. However,
I think I have devised a way. I'll keep you posted if you're interested in
reviewing it.
