  r57158 | facundo.batista | 2007-08-17 12:16:44 -0700 (Fri, 17 Aug 2007) | 9 lines


  Added a flag (_send_traceback_header) to the SimpleXMLRPCServer class
  that allows sending back exception/stack trace information about
  internal server errors (this flag defaults to False to avoid sending
  such information unless explicitly enabled).  Added tests to verify
  behavior of this new feature (these tests are skipped on win32 because
  of problems with WSAEWOULDBLOCK). Renamed HTTPTestCase to
  SimpleServerTestCase. [GSoC - Alan McIntyre]

  up when the world around it has already been destroyed.
