If your intend is to try minimizing swapping, trying to keep in RAM as
much as possible, why not using the swappiness kernel configuration?
See:
% 'grep' swap /etc/sysctl.conf
# Start looking at using swap only when ram has that % left.
vm.swappiness=6
That means, attempt to start using swap only when there's 6% remaining
free RAM. Now, it's NOT guaranteed that's what the kernel will do,
it's just a hint. You can look on the web for swappiness, you'll find
all kind of blogs and comments...
That might help minimize the use of swap area...
