Yep. That is the plan.

Heh. I knew I shouldn't have mentioned it.
This was actually one of the first things that impressed me about Cygwin
when I first started using it. Of course, when I first started it only
worked about half the time, but still...
The way I'm implementing this you should be able if /dev/consN is
actually associated with a console but you won't be able to do anything
other than verify existence.

I actually have the /dev/cons<small number> about 3/4 finished.
If we do decide to get rid of CYGWIN=tty then /dev/cons may become
/dev/tty<small number> again and ptys will become /dev/pty<small number>.
