 been very slow to appear in end-user distributions, I continue to
 provide this (simpler) solution via SourceForge for those who need it. 
For reference there are alternative ways to gain access to the rlimits
functionality which don't rely on updated PAM (or login on PAM-less systems
such as Slackware). Set_rlimits, available at
  
http://www.physics.adelaide.edu.au/~jwoithe/set_rlimits-1.2.0.tgz
is one alternative and has the advantage of operating on a
per-user/per-application level rather than a per-user level (ie: elevated
limits are set for users/groups running specified applications only).  Yes,
it's slightly less convenient but it works and is arguably more secure.
