    Sorry! Should have better read the documentation: it states that
memory locking is removed when executing a new program. Therefore the
method does not work; the call to mlockall() must be done by the daemon
itself, unless using artefacts like containers, which I'm not familiar
with. Anyway I could not test my program because I don't even know how
to check if memory locking is in effect.
