under completely normal operation when programs fit in real memory
swapping CAN occur because of file caching.
while programs have priority over file cache in memory, long-unused parts
of system can be swapped out.
i don't know what's nagios, but configure it to warn you not because there
are swap used, but if there is more than a little swapping activity.
