This is what I am playing with on the OS/2 systems.

Well I wouldn't be all that happy about mlock(). In 99.99% of applications
if data is swapped to disk it doesn't matter. I would hate to think of a
system where all the apps were locking memory and preventing the OS from
doing it's memory management functions.

IMHO if the swapfile is a serious security risk then one should disable it
or put it on an encrypted disk.
