-Pl_mom is organized as two processes. The reboot process runs every
-second, and the slice reset process runs every 30 seconds. The reboot
-process is very lightweight and only reads /proc/swaps. However, the
-slice reset process may pull data from the slicestat sensor on port
-3100, which can potentially take a long time (on the order of minutes
-if there are thousands of processes on the machine).
