This report is quite confusing -- without more evidence it's difficult
to have something to go on. I can reproduce a panic in -CURRENT with
forkbomb as the submitter describes, but it looks like a diagnostic;
running forkbomb as a non-root user doesn't panic the machine due to
the proces limit.

The panic is pretty much as I'd expect. It would be good to harden things
a bit more along this path, but from reading CVS history for these files it
looks as though the behaviour was changed to avoid a lock-order reversal.
