 // When frame content is replaced, all subframes are destroyed. This happens
 // in FrameLoader::detachFromParent for each subframe.
 //
 // Frame going away causes the FrameLoader to get deleted. In FrameLoader's
 // destructor, it notifies its client with frameLoaderDestroyed. This calls
 // WebFrame::Closing and then derefs the WebFrame and will cause it to be
 // deleted (unless an external someone is also holding a reference).
