:Hmm, why bzero at all if you are just going to free it?  Why not move the bzero
:to an else after the ISDYNSTRUCT check?  (Not that this is really all that

    He is invalidating the structure to catch references to deleted sbufs.
    (see assert_sbuf_integrity() calls).

    Josef, I take back my last request... I think there's another bug.
    Your vmstat -m output showed that both the sbuf pool and the VFS cache
    pool were blown up.  The fix I just made will probably only solve the 
    sbuf pool issue.  If you still want to test it, observe both pools
    in the vmstat -m output carefully!
