[ale] take a trip through your process list - hot pc

[Jim Kinney]

My current desktop is ram limited and I run firefox with a zillion tabs in
a million windows. It will eat up the ram then happily punt out to swap.
Page not touched in 3 hours may take 2 secs to reload but that's OK with me.

Get's fun when something crashes firefox and it reload all the windows and
tabs :-) First time I've been on a desktop class system instead of a server
class system as a desktop.
