I think that if you're running at the same level as ip_debug, you
shouldn't have an irrational fear of mdb, even with the "-w" option.

If you do have that fear, or if you need any sort of comprehensible
output, then you're better off in dtrace.  If nothing else, you'll
have *MUCH* lower overhead.  (There are few better ways to turn a
working busy server into a slug than to issue an errant "ip_debug
10".)
