 // This class provides an implementation the
 // HungWindowDetector::HungWindowNotification callback interface.
 // It checks to see if the hung window belongs to a process different
 // from that of the browser process and, if so, it returns an action
 // of HungWindowNotification::HUNG_WINDOW_TERMINATE_PROCESS.
 // Note: We can write other action classes that implement the same
 // interface and switch the action done on hung plugins based on user
 // preferences.
