Something is wrong with the 2.4 VM. As of yet, it cannot reclaim
swap space once it is full. This is pretty much the next thing on
my TODO list, right after the worst highmem lockups and balancing
issues have been fixed.

Watch http://www.surriel.com/patches/ closely, swap reclaiming is
next on my TODO list ;)
