  Revision 1.1.2.6  2002/09/09 22:11:51  dgrisby
  SSL transport cleanup even if certificates are wrong.

  Revision 1.1.2.5  2002/08/21 06:23:16  dgrisby
  Properly clean up bidir connections and ropes. Other small tweaks.

  Revision 1.1.2.4  2001/07/31 16:16:22  sll
  New transport interface to support the monitoring of active connections.

  Revision 1.1.2.3  2001/07/13 15:36:53  sll
  Added the ability to monitor connections and callback to the giopServer
  when data has arrived at a connection.

  Revision 1.1.2.2  2001/06/20 18:35:16  sll
  Upper case send,recv,connect,shutdown to avoid silly substutition by
  macros defined in socket.h to rename these socket functions
  to something else.

  Revision 1.1.2.1  2001/06/11 18:11:06  sll
