I think of it more as protecting user jobs from other users who are
new to HPC and probably well meaning (or desperate to get jobs running).

As the users project here get allocated service units and charged for
compute time in those units we have a duty to make sure they are
getting the time they've been allocated.

Some of them are quick to let us know if a users job has managed to
escape from Torque's cpuset controls for instance (we had a weird
issue here that caused that for a bit).

cheers!
