Comment 1 for bug 617598

You can't run two shutdown calls at the same time.

The remote.py script in ec2 test call 'sudo shutdown -P now' when the test suite has finished. However, we already put a shutdown in place as an earlier 8-hour failsafe. The failsafe shutdown blocks the end-of-suite shutdown from happening. Thus the server stays alive for the full test run.

Evidence:

ec2test@domU-12-31-39-0E-62-61:~$ sudo shutdown -P now
shutdown: Another shutdown is already running
ec2test@domU-12-31-39-0E-62-61:~$

To solve this I can cancel the existing shutdown with 'shutdown -c', then call it again with '-P now'.
