        REGRESSION (WebKit2): window.showModalDialog() broken

        If dispatching a message ends up creating a nested run loop, some incoming messages can end up not being
        delivered until we exit from the run loop.

        Fix this by using a Deque instead of a Vector for incoming messages, and get one message at a time and then
        dispatch it. That prevents us from having any lingering messages lying around in stack allocated space.
