Roughly a hundred years ago, I wrote a program that does this.
I suspect that it still works on VAX/VMS; I suspect that it would
take some effort to port it to Alpha/VMS.

You can find it on Arizona.EDU in 
ua_source:[vax.job_daemon] ; VMSINSTAL kits are in
ua_source:[vax.job_daemon.vmsinstal].

Its main function is to be an idle job killer, but it
also fiddles with "CPU hog" process base priorities.
Either function can be disabled as desired.

Actually, now that I look there, I see that there were
some semi-serious bugs that Tony McCracken fixed but
never got merged back into the kit (see mccracken.fixes.)
So use this at your own risk.

Cheers,

Aaron
