I do agree that processes that start up and never get 'touched' again should
definitely get swapped out, but only when system ram is nearing the low point.
At this point, processes who haven't used memory the longest should get
swapped. For example, I have 24 /sbin/mingetty processes that listen on that
32mb system. Most of the time, except when I'm _really_ busy, I only use 6. :-)
Also, one other thing I noticed (in the old VM, haven't noticed it on my 32mb
machine yet) is that when processes get swapped out, doing a 'ps -aux' prints
the SWAP values correctly as '0'. But doing a consecutive 'ps' shows these
processes as '4'. Is there something new in recent kernels that getting process
states actually has to access a page of the process's RAM? Just curious.
