Details
It would be nice to know if a page fault may have been responsible for a BHR hang, since that would decrease the value of the stack associated with that hang. We could probably just check the page fault count every time we're notified of activity, and if the number increases during a window where we had a hang, then annotate with that number?

Be careful: if we're paging because Firefox itself is using lots of memory, that's different from if other parts of the system outside of our control are using memory. Also, single paging events are much different from many pages/continuous paging. So I'd encourage you to refine the question a little bit.
