My humble understanding is that this is not a per-process action,
but it acts on the whole system. I'd like to be mistaking, which would
prove one can act on this through /proc<process-id>
OTOH, I have checked that calling mlockall() does actually lock
memory pages, and also that it does not survive execve() -- as can be
checked with 'grep VmLck /proc/<process-id>/status' . Therefore, my
understanding is that the daemon must either call mlockall() itself or
run inside an environment where swapping is disabled for all processes.
