If you use bash, you could put "ulimit -Hu <number>" and "ulimit -u
<number> in /etc/profile. I think your kernel may also need the quota
option or so. You could try
ulimit -u 1
man ulimit
to see if it works.

now set your ulimit back up to something reasonable and read man bash.
There is some sketchy provision for it to be set in the GECOS field of
/etc/passwd, but I couldn't work out the format. I reckon putting it in
/etc/profile should do. Other distros may keep the bash startup file
somewhere else, but man bash should tell you where. This is SlackHat
4.9. YMMV.
