Being a newcomer to the NeXT sysadmin game, I'm not sure if I have a  
handle on the way the swapfile works, especially under NS 3.0.  Here's my  
situation:

I noticed that swapfile.front doesn't ever shrink.  For instance, it grew  
large (~8MB) after I did some extensive playing around with BackSpace.  I  
expected it to shrink after I quit BackSpace, but it didn't.  Now I don't  
remember whether swapfile changed size at all (I have it set lowat=16MB).

Swapfile.front returned to its small (~2MB) size upon powerdown/powerup,  
but didn't shrink after a hot boot (Alt-Cmd-*).

Can somebody shed some light on what's going on?

Thanks,

James

Swapfiles, like entropy, never shrink spontaneously.
Reboot plays the role of Maxwell's demon!
