The following additions to /etc/security/limits.conf will help:
abusername hard priority 19
abusername hard maxlogins 1
abusername hard nproc 2
This will limit him to a single login with a maximum of two user processes
(lower and he might not be able to type commands at the console at all),
with an enforced priority of 19 for all processes.
You can also consider RSS and CPU time limits, but those are secondary.
You may also want to consider putting appropriate ulimits into
/etc/profile. However, if /etc/shells allows a shell which doesn't source
/etc/profile, ulimit won't be as enforcable as PAM.
