False.Genesis 6c4ae79a87 * rewrote the realm/world login code.
-> reconnecting does work now, finally.
* updated conf setting: reconnect=0: dont reconnect; reconnect=X: reconnect after X msecs.
* misc code cleanups, crash fixes, and overall improved stability.
* splitted RealmSocket into a RealmSession and the original RealmSocket code. better read-/useabilty because now its handled as WorldSession and related.
