00027 //       Class : QueuedConnectionManager
00028 // Description : This flavor of ConnectionManager will queue up all of
00029 //               the reset-connection messages from the
00030 //               ConnectionReaders and ConnectionWriters and report
00031 //               them to the client on demand.
00032 //
00033 //               When a reset connection has been discovered via
00034 //               reset_connection_available()/get_reset_connection(),
00035 //               it is still the responsibility of the client to call
00036 //               close_connection() on that connection to free up its
00037 //               resources.
