Sounds to me like quotas aren't really what you want, either.  You don't
want to set artificial limits on people's work (and any limit, no matter how
high, is going to be a problem for someone someday).  What you really want
is an OS that doesn't make it nearly impossible to deal with exceptional
conditions.  UNIX's response to a filled disk comes from the "panic:  out
of swap space" days when nobody really wanted to write the tough code because
it wasn't that important.  If Berkeley (or AT&T) would put as much effort into
the disk-full problem as was put into "swkill()" in 4.2, I bet you'd happily
stop using quotas.
