Ticket 48930 - Paged result search can hang the server
    
    Bug Description:  If a pages result has sent all its entry it's possible that
                      the connection lock/monitor is not exited.  This can lead
                      to a deadlock when a new connection comes in.
    
    Fix Description:  Move the monitor exit to the proper location, and also set
                      the result to success if all the entries have been sent.
