+This test logs in, waits a random interval between 0 and 120s, then
+automatically reboots power to the system using a remotely controlled power
+strip. After the system restarts, it verifies that login completes and
+cryptohome mounts successfully. Best used on an account with many things to
+sync, so the crash happens during various stages of the syncing process.
+This test runs continuously and fails iff it stops running.
