[torqueusers] Memory allocation issues

I'm having problems with my users crashing compute nodes due to code 
bugs and poor coding. Even when they request -l mem=xyz they can still 
oversubscribe a node and crash it due to memory over subscription. Other 
users are becoming frustrated because there are frequently 2 or 3 jobs 
on a compute node and any given time. Is there a way to effectively jail 
in a process and subset of processes so that they cannot use more than a 
given amount of memory?
