Are you sure this is a good idea?  Not only is it non-portable, but
there's a lot of alternatives.  For instance, the front end probably
wants to create the PTY with its other end pointed somewhere useful,
and in some frontend-private namespace.  A text-based front end might
want to connect the PTY to an already running screen session.  And so
forth.
