Caught this weird leak in a try build:

  https://treeherder.mozilla.org/logviewer.html#?job_id=19805770&repo=try

Just before the leaks I see this in the log:

Seems at the end of the service worker test directory we failed to gracefully shutdown the browser.  So we leaked a bunch of stuff.  I'm sticking this in service workers component, but not sure its really at fault here.
I get similar messages logged to syslog when I close FF 51.0.1 production release (official ubuntu 16.04 package). To reproduce this issue it is necessary to tweak the apparmor profile which is shipped with the FF package.

To tweak the apparmor profile, I applied "VERSION 6" of the patch, taken from here: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988
