All Win64 e10s tests are going to permafail when Gecko 48 merges to Aurora
[Tracking Requested - why for this release]: Mass win64 e10s test failures when Gecko 48 merges to Aurora. I'm assuming this is sandboxing-related since it's win64 e10s only and there's sandbox-related stuff on those stacks. Does any of our sandboxing code depend on NIGHTLY_BUILD? https://treeherder.mozilla.org/#/jobs?repo=try&revision=5b3d47649e85&filter-searchStr=windows%20x64%20e10s&selectedJob=19232603 Sample log: https://treeherder.mozilla.org/logviewer.html#?job_id=19232603&repo=try
NIGHTLY_BUILD is used to set MOZ_CONTENT_SANDBOX and prefs. What specifically is the "sandbox-related stuff"?
