Description
- Start the appserver on windows in debug mode, listening for a connection
  from a debugger. 
- Connect from a debugger, eg, jdb.  Note that the connection succeeds.
- Quit jdb
- Connect a second time.  The connection is not established and no
  debugging can be done.

This failure only occurs on windows when the socket transport is used,
and the debuggee launches another application with Runtime.exec().

EVALUATION ###@###.### 2004-04-10 On windows, the socket is inherited by the child process. This causes the socket to remain in use after the first debug session is terminated.
