https://treeherder.mozilla.org/#/jobs?repo=try&revision=6cc5fb3fbff4381b35bab487a9cd74a9c668b764 was an attempt last week to make these run on win8 instead, and it worked well. So if the orange rate is too high we can switch them to win8 if need be.

Comment on attachment 8893551 [details] Bug 1373567 - Schedule JSReftest on win8, and demote win10 to tier 3. https://reviewboard.mozilla.org/r/164628/#review169978

Wes, if you think this intermittent is bad enough to want this patch on central, can you autoland please. in the meantime RyanVM is planning to land on beta.

Landed on Beta to reduce some noise. https://hg.mozilla.org/releases/mozilla-beta/rev/68b791c2971a
