CentOS - Dec 2011 - Seeing rlimits on CentOS 4

This is probably something any SA should know... but I don't!

On CentOS 5 I can see what a process's current soft and hard
limits are; /proc/<pid>/limits

However this isn't in the C4 kernel.  Is there any easy way of determining
what the process rlimit values are?

% uname -a ; cat /etc/redhat-release
Linux c4 2.6.20.7 #3 Sun May 2 16:30:15 EDT 2010 i686 i686 i386 GNU/Linux
CentOS release 4.8 (Final)

(yes, I know this machine should be updated, but...)

That's not a CentOS-4 kernel...
kernel-2.6.9-101.EL is the latest released

OK, that was a usermode linux kernel.  Here's a machine with 4.5 instead
and 2.6.9-55.9.ELsmp

I can't upgrade these machines in a reasonable time period (production
outage on core infra?  Ugh) and need the values on the current systems.

(Huh, interesting, 4.6 with 2.6.9-89.0.9.EL does have /proc/<pid>/limits)
