So, my question is: does it surprise anyone that tasks posted via callOnMainThread() are getting executed even though there's a modal dialog shown? And is there anything I should be doing in my task handler to make sure we aren't re-entering JS execution inappropriately in these cases? I'm just concerned that the way we're posting tasks from worker threads to the main thread may cause reentrancy problems.
It is not correct to deliver messages from worker threads when an alert or a modal window is displayed. It may be ok for modal dialogs that are triggered asynchronously (such as credentials dialog).
We have a manual test regression for a related issue, WebCore/manual- tests/js-timers-beneath-modal-dialog.html. You can compare how timers work, and how worker messages are delivered to find out how to fix the problem.
