ulimit would limit total CPU time if thats what you are after.=20

I run a programme in the background which monitors all the instances
and renices them dynamically. Heavy users get niced heavily. It uses a
simple ruleset so that heavy users who are reniced can be reniced back
to normal again if their usage returns to normal. This works well in
my network (50+ instances over 4 machines). The code is integrated
into my site, so I cannot send you the code, but it was quite easy to
write. This gives "fair usage" to the instances, without an arbitrary
CPU time limit.
