 * When a torrent changes its info-hash, this alert is posted. This only happens in very
 * specific cases. For instance, when a torrent is downloaded from a URL, the true info
 * hash is not known immediately. First the .torrent file must be downloaded and parsed.
 * <p/>
 * Once this download completes, the ``torrent_update_alert`` is posted to notify the client
 * of the info-hash changing.
