From bug 1375281, comment 14 we would like to stop always observing the cc-end notification. Instead we want to: #1 - Register for notification #2 - Get notified, unregister #3 - Dispatch the idle |gatherMemory| request #4 - Issue a setTimeout to re-register at the end of |gatherMemory| This will hopefully avoid redundant round trips where we observe the notification, calculate the amount of time that's passed and then ignore the notification.

Instead of improving how to use the notification, could we directly record memory measurements into Telemetry from the CC (at some interval)?
