Comment on attachment 119580 [details] WIP The change looks good so far, the only issue I have is that it is hard to understand :) Maybe you could put more comments in the change log, regarding: 1) why m_mode fields are removed 2) the lifetime of WorkerFileSystemObserver and why the bridge is no longer an Observer 3) Some sort of "proof" that m_workerContextObserver only gets deleted on worker thread (ASSERTs, even?)
Comment on attachment 119580 [details] WIP View in context: https://bugs.webkit.org/attachment.cgi?id=119580&action=review Awesome, it's really great to see the tests for this complex worker termination sequence. The code looks good to me (as far as I understand). > LayoutTests/http/tests/workers/terminate-during-sync-operation.html:39 > +function waitForAllWorkersToStart() This name may sound a bit confusing as its main purpose is to start sync ops after making sure everyone is started? How about startAfterAllWorkersStarted or something? (I'm not good at naming though)

So the people can figure the purpose of the test w/o looking at the several related bugs.
