It stops scheduling. (RQS doesn't enforce it in the sense of setrlimit,
but there's a default specified in our case.)
Specifically, with a rule like this:
limit users {!@longusers} to h_rt=432000
serial jobs with -l h_rt=432000 will run for all users, but parallel
ones won't for users not in the ACL (due to that limit according to
qstat). Two slots with half the h_rt will run.
