BackgroundHangMonitor uses around 10% CPU on my Windows machine for stack collection, when I am running heavy benchmarks.
It would be nice to be able to disable it for more stable benchmarks.

There's a r+ patch which didn't land and no activity in this bug for 2 weeks.
:miko, could you have a look please?

Miko, could you clarify why this only disables BHR in content processes? It's not altogether clear to me from the patch or this bug.

The motivation behind adding this pref was to get cleaner profiles during benchmarking. On my machine the content process was the only one where this stack collection was taking excessive CPU time.
