We're seeing flakey results on animations/suspend-resume-animation.html
http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=animations%2Fsuspend-resume-animation.html
Dean marked the test as flaky in <http://trac.webkit.org/projects/webkit/changeset/163624>.
See also bug 50959: animations/play-state-suspend.html also became very flaky at the same time.
There are more tests that regressed - they were already marked as flaky, but became much much more so in the last week: animations/stop-animation-on-suspend.html (bug 49182) animations/combo-transform-translate+scale.html (bug 122040) With more tests to cross reference, it appears very probable that the failures started in this short range: http://trac.webkit.org/log/?verbose=on&rev=163476&stop_rev=163472
These only fail in debug mode on test bots, but at least animations/stop-animation-on-suspend.html became flaky on EWS too. I'll remove [ Debug ] from TestExpectations.
