   Is there any way to kill all instances of a process that has the

      while (1)
	 fork();

For BSD, if you've got a super-user shell handy, you can send SIGSTOP
signals to all of the offending processes using something along these
lines:

	ps tXX | grep -v PID | awk '{print $1}' | xargs kill -STOP

Once the forking (:-) processes have been stopped, they can be
terminated at leisure by hand or using a variation of the above
pipeline.
