//       Class : QueuedConnectionManager
// Description : This flavor of ConnectionManager will queue up all of
//               the reset-connection messages from the
//               ConnectionReaders and ConnectionWriters and report
//               them to the client on demand.
//
//               When a reset connection has been discovered via
//               reset_connection_available()/get_reset_connection(),
//               it is still the responsibility of the client to call
//               close_connection() on that connection to free up its
//               resources.
