---------------------------------------
Committed a fix for the second log snippet that Jie posted around the test bug.

commit 28eaa8df7c95130b0c244f7613ad506be899cafd
Author: Anand Mazumdar <an...@apache.org>
Date: Wed Dec 14 17:40:47 2016 -0800
Fixed the 'IOSwitchboardTest.KillSwitchboardContainerDestroyed' test.
The container was launched with TTY enabled. This meant that
killing the switchboard would trigger the task to terminate
on its own owing to the "master" end of the TTY dying. This
would make it not go through the code path of the isolator
failing due to resource limit issue.

The original log in the issue description is a separate issue in the
switchboard code itself and I am working on that. This should make the CI green
for now.
