O, you need to actually get a new tty. Windows doesn't have the concept
of a tty. File descriptor redirection is fine. Maybe we could have
something like

   gdb --i=mi --out_fd=n
where n is the descriptor you plan on reading from GDB.

What does it mean to open a 'tty' on a windows platform, or some other
non-unix platform?
