Review comment:
currentNotify has to be cleared in either case, there's no need to keep it
around any longer. Either a suspension was aquired at this point or not.
Actually we have to move the _suspended counter into the scope of
currentNotify, otherwise we run intro troubles with parallel Ajax requests.
