We had a couple issues with both shutdown and startup:

   https://bugzilla.mozilla.org/show_bug.cgi?id=705761

   https://bugzilla.mozilla.org/show_bug.cgi?id=701909

The 1st is likely to be fixed now, and possibly the 2nd, but it's not 
clear if we're sometimes seeing some issue at startup.  Telemetry will 
tell us.
