The particular crash you linked to there is a dupe of the CompositorThreadHolder::Shutdown() shutdown hang.

More broadly, I think the problem here is that mozilla::PrioritizedEventQueue<T>::GetEvent needs to be added to the irrelevant signature list, as was done for a variety of other event queue signatures in bug 1402037. I'll file a bug for that.

Hey Will, do we have any open bugs on adding to those skip frames? Looks like we found another uninteresting middle frame here.

Yes, I fixed that in bug 1409425.

That fix for bug #1409425 went to production earlier today. I reprocessed 

https://crash-stats.mozilla.com/report/index/b969897a-451c-4186-9c6d-514de0171017?refresh=cache

and it's got a different signature now:

shutdownhang | mozilla::layers::CompositorThreadHolder::Shutdown

Hope that helps!

This signature should be gone now, so I'll close this bug.
