If I'm not wrong, access to the queue can be a race condition across syncRemoteContent and some methods of LayerTreeCoordinatorProxy that update it from the main thread, like setContentsSize or setVisibleContentsRect. Those are used by public API so we should not take any preassumption about when will they be called.
