2e641ab995b3 mod_cloud_notify: added code to respond to the new event "smacks-ack-delayed" issued by mod_smacks when acks are delayed for a certain amount of time. This allows to send out notification requests before the read timeout or connection close event really happens, thus allowing conversations to be smoother.
