Unlimited locked memory has the problem that one process can lock all your
available ram. Which in itself will almost kill your system as everything has
to be swapped out. And adding more swap will not help then to get your system
back as all ram-memory is locked in place. Instant doom.

Distributions seem to add unlimited memory-lock as default but I think that is
only because they don't know your memory. Would be fun if they created the
limit to 1/2 or 3/4 at installation time.

Have fun,

Arnold
