    307. [bug] When canceling a query, the resolver didn't check for · 96ab2529
    David Lawrence authored
    			isc_socket_sendto() calls that did not yet have their
    			completion events posted, so it could (rarely) end up
    			destroying the query context and then want to use
    			it again when the send event posted, triggering an
    			assertion as it tried to cancel an already-canceled
    			query.  (RT #77)
    
    ... so now the resolver counts the number of outstanding isc_socket_sendto()s
    and only destroys the query context when there are no more.
