/**
 * Queue handler for pre-processed outgoing XMPP messages.
 * Formatted XML stanzas will have been pushed into the queue
 * via the Queued_XMPP connection proxy, probably from some
 * other queue processor.
 *
 * Here, the XML stanzas are simply pulled out of the queue and
 * pushed out over the wire; an XmppManager is needed to set up
 * and maintain the actual server connection.
 *
 * This queue will be run via XmppDaemon rather than QueueDaemon.
