But you'd
need kernel mode for that; this is a DoS attack (one of the
first?) launched by a user.
The userland DoS I remember:
main() {
while(1)
fork();
}

It can be made less disastrous by judicious addition of a wait(); call.

Not necessarily pathological. I have students do it all the time
in the early parts of the Operating Systems Course. The only one
it denies service to on contemorary UNIX is the individual who does
it. Process limits are by user, not by system.
