In the next release I try to include a pointer that explains a little
what locked memory is and what implications there are to increase
the available amount of locked memory to users.

No, this is not helping. The amount of locked memory available to users
would not change.

What exactly you enable with pam_limits.so is configured and documented
in the file /etc/security/limits.conf.

Well, I try to make some of the stuff in README.Debian more easy to
understand with the next release. The _real_ problem is, though,
that there are a lot of unrelated errors when locked memory is short.
I even had segfaults. Perhaps the best handling would be to make sure
enough locked memory is available before starting the program.
