I've been able to solve such problems by adding a limit on the number of processes per user, but that really only works because my environment is limited. I can imagine trying to write a daemon that would monitor usage and kill processes if they exceeded usage. It's a clunky solution, though. > PS: I wasn't sure if I could address this on freebsd-arch, so it's going here. If you're offering to write kernel modifications to do it, then you should take it there. Otherwise, this probably is the right place.
