this is debug/e10s and osx/win8 primarily. I did some retriggers to help find the root cause here: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&filter-searchStr=debug%20e10s%20osx%20bc2&tochange=0aac487103cebe31b430b44d21b89720fc3989ef&fromchange=4031cd5354cfac3db99b6e7c440639243c9f86cd&selectedJob=82063444 here is a screenshot from the first occurance: http://mozilla-releng-blobs.s3.amazonaws.com/blobs/mozilla-inbound/sha512/0ee8cddcfa4173af7d39b874dc4c8db38ecc1bc2f3fc06b0cf74959e82fade9ff32eb83920a312a7d656c698937c9c53b1b2a414e9c0ec8022e7d2823049ba73 and from the log: https://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-inbound-macosx64-debug/mozilla-inbound_yosemite_r7-debug_test-mochitest-e10s-browser-chrome-2-bm136-tests1-macosx-build11.txt.gz and the output of this test in the above log: 19:59:55 INFO -

Maybe do: let loaded = awaitLoad tabs.create yield loaded If you feel that's not a problem I'm fine.

this is still failing at a similar rate- I was optimistic we had fixed this- the failure messages look the same. :mixedpuppy, can you take another look at this?

I don't think kris landed the patch.
