+and no cancel can overtake it there (the queue offers work again after an error, and a cancel of an ask not yet
+recorded is dropped); once expired, the router refuses it if taken late. A refused question keeps none of
 its words. An answer is the operator's word to the session and authorises nothing; a question never defaults.
