In genuine UNIX(tm) systems, there is a per-user process limit,
so eventually the fork requests start failing.  However, this
program keeps trying to fork, so if you kill off some of the
child processes it will spawn replacements.

I don't think it counts as a proper "denial of service" attack,
since it affects only the invoking user (well, it does bog
down the system with swapping etc. but again, per-user resource
bounds can address that).
