Details

Every so often, we need to analyze code that spins the event loop from JS. For instance, bug 1248819 shows that some such code causes a shutdown hang/crash, but we have no idea which JS code is running.

It would be great to have a way to instrument `nsIThread.processNextEvent`, when it is called from JS, to somehow label it with the JS stack.
Noting we have a top crash on a couple of releases running (45 and 46) that fit this criteria.
