The per process limit on locked memory is not implemented.
(The shared system wide limit works though).
Until this will be eventually fixed manpages
getrlimit(2) and mlock(2) should note this in their BUGS section!

Also mlock/munlock are (currently) only available to the superuser
and return EPERM if called by a mere mortal. This behaviour should
be _documented_ in mlock(2).

>How-To-Repeat:

1. Call mlock() from non-root process => fails with EPERM.
2. Set RLIMIT_MEMLOCK to a small value. Mlock much more => works.
