A case in point is a system that I have with 1gb of
ram  (redhat 7.3)

Mem:  1030676K av,  941356K used,   89320K free,      
0K shrd,  188652K buff
Swap: 2097136K av,     976K used, 2096160K free       
          618692K cached

Even after 2 days it's started to use swap, so as you
can see a system will use swap even if there is Mem
free. I have also noticed that the longer the system
is running the more swap it use's (although it's yet
to use more than 5%).
