// Bug 709759 - Test the stop ability of <iframe mozbrowser>.

// The img that is loaded will never be returned and will block
// the page from loading, the timeout ensures that the page is
// actually blocked from loading, once stop is called the
// image load will be cancaelled and mozbrowserloadend should be called.
