The exact quote is "Not used.", and yes it is wrong.  There are some fields
which aren't used, or enforced, but most of them are.  Perhaps Robin
Wilson could post the definitive list of fields that are initialized in
/etc/security/limits as well as the list of resource limits that are
actually supported by the system.

The ones which I can think of right off the top of my head that are
mostly ignored are "rss" and "cpu".  I know that "stack" and "data" are
enforced because setting illegal values does prevent programs from
executing.  I know that "core" is enforced (but perhaps not initialized
from the /etc/security/limits file) because you can set it to a very
small value and inhibit core dumps.

This question is definitely one for the FAQ posting for this group.
