I wanted to know if it was possilbe to make a process non swapable.
This was to be a tmp messure to solve an urgent problem, luckily the
software that was causing the problems has been turned off and will be
moved to another machine so I didnt need to do anything. The answer
is:

1) If you have the source code there are a few systems calls to use:
mlock mlockall plock

2) If you only have the binary the only thing to do is run the process
at a high enough priority so it doesnt get swapped out.

Thanks to all

BB
