The problem you mention is not due to Franz Lisp but is done by
the 4.2 Kernal.  I can't speak for Berkeley since I've NEVER run on
a vanilla BSD machine, but here at Purdue (ECN) the kernal kicks each
proc's nice up to 4 after chewing up 10 minutes of CPU time.  The
idea is to give large crunchers lower priority so that they don't
impact interactive users.

Because we have lots of users that run large jobs we have taken it
even farther and set a "research" bit that gives long running jobs
even lower priority.  All in the name of keeping the big crunchers
from taking over the machine....
