Overview
--------

"Pl_mom cleans up your mess" by resetting slices that are using up too
much memory, and by rebooting the machine once the swap space is
nearly full.

Specifically, swapmon takes the following actions based on the amount
of consumed swap space:

* at 80% full, swapmon starts logging the available swap space to
  syslogd, restart largest slice and send mail.

  After 3 restarts, kill slice.

* at 95% full, swapmon reboots the machine and sends mail to the pl-mom
  alias
