%description

A small daemon that watches the consumed swap space.  At 90% utilization, it
resets the slice that is the biggest memory hog.  At 95% utilization, it 
reboots the machine.

A cron job which "fixes" various common problems with nodes (dead
services, ext3 corruption, zombie SSH sessions) is also installed.
