Here are some related speculations, none of them validated in any way
- opening a window station is only needed when running as a service.
  MS may not handle correctly the case where we are at the console.
- cygwin does not specify the name of the station, it uses the default
  which uses the logon session identifier. I think that all users of
  the same service (e.g. inetd) get the same station.
  For example when I telnet in twice, both instances see the same 
  clipboard, different from the console clipboard.
- so it may be better to only create a window station when opening the
  *master* ptty when running as a service (the process is then in the Admins  
  group), and to specify a unique name.

P.S.: I saw the recent ChangeLog 
 (shared_info::initialize): Don't initialize user stuff if myself doesn't exit.
 and have been scratching my head about why it's helpful.
