        Async event handlers should not fire within a modal dialog
        https://bugs.webkit.org/show_bug.cgi?id=53202

        Asychronous events that use EventQueue would currently fire while a
        modal dialog (e.g. window.alert()) was up. Change EventQueue to use a
        SuspendableTimer (which automatically gets suspended while dialogs are
        up and in other cases where JS execution is not allowed).
