Why go to such troubles? You can often make a box just as comatose
(though you should not be able to crash it) with the following command:
$ perl -n /dev/zero
(Of course this only works on systems with /dev/zero.)
As with the other method, limiting/reducing a user's max. process size
will reduce the ill effects from this...
