Memory consumption on a per user basis [FOLLOW-UP]

I hit _send_ to quickly... The simple script that I proposed suffers
from the problem that it would kill one of your own processes if you are
the offending user, ont one of your students; likewise, it would
blithely kill a system process, or an essential cronjob, or a server.

You can modify the 'smem' command to use its 'user filter' option (see
the man page) to come up with a regex to limit its output to just those
users whose processes you are comfortable killing. The regex can be as
simple as (user1)|(user2)|...|(usern) ; I don't see how to use UID
numbers, but it might be possible.

  smem -U "$YOUR_REGEX" -c pid | tail -n1
