First, you could purchase a batch queuing system (like NQS) which does
automatic non-aging priorities. Second, you could do it yourself with
the npri(1) call. See the man page for this. Last, you could make a daemon
which greps the CPU time of, lets say, more than 1 hour and sends a STOP signal
to there if you log in to the console.
