[mac-debug] LayoutTest storage/indexeddb/objectstore-cursor.html is a flaky timeout https://build.webkit.org/builders/Apple%20El%20Capitan%20Debug%20WK2%20(Tests)/builds/7996 https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=storage%2Findexeddb%2Fobjectstore-cursor.html
Marked test as flaky in https://trac.webkit.org/changeset/205514
First instance of the timeout according to the flakiness dashboard was ~r204949
The test doesn't appear to be failing flat out, but rather it actually takes a very long time on debug builds. (It's not *great* on release builds, either) I have some ideas for improving cursor performance, but in the meanwhile this doesn't really concern me as an inherent correctness problem.
