This can be resolved by emptying the scheduler's sample queue before requesting the scheduler thread to finish. This will make sure the scheduler thread returns to it's main loop quickly, and can handle the termination request. 1142828 1 265745 peavo 2015-11-18 07:38:12 -0800 Created attachment 265745 Patch 1142868 2 265745 commit-queue 2015-11-18 10:25:02 -0800 Comment on attachment 265745 Patch Clearing flags on attachment: 265745 Committed r192578: <http://trac.webkit.org/changeset/192578> 1142869 3 commit-queue 2015-11-18 10:25:04 -0800 All reviewed patches have been landed.
