I have found another problem with the latest change which seems to
be related to the CYGWIN=tty setting. I'm getting this (or a very
similar output) when trying to logon from another box using ssh or
when I start anything using `sh -c', both with CYGWIN=tty:

$ sh -c ps

      0 [main] ps 1108 fhandler_base::fork_fixup: /dev/tty0 - Win32 error 6, handle io_handle<0x16C>
   8637 [main] ps 1108 fhandler_base::fork_fixup: /dev/tty0 - Win32 error 6, handle output_handle<0x170>
  18431 [main] ps 1108 fhandler_base::fork_fixup: /dev/tty0 - Win32 error 6, handle output_done_event<0x138>

  88439 [main] ps 1108 fhandler_base::fork_fixup: /dev/tty0 - Win32 error 6, handle io_handle<0x1B4>
[...]
The whole output is generated three times just with different handle
values (stdin, stdout and stderr, probably). Then the normal `ps' output
appears. Generally, the above ERROR_INVALID_HANDLE output appears,
then everything works fine. That's also valid for the aforementioned
ssh session. As usual nothing happens when started under strace control.
