Well this code is very much in flux so I really don't want to get further
changes mixed up into the plan at the wrong moment. That said:

This fits very well with where I want to end up - which is


	tty = driver->ops->something(driver, idx);

and thus punts all the pty crap from the tty lookup into the pty driver.

So I think this is looking good as a direction, and once the pty crap is
in the pty code it is much easier to localise all the devpts magic.
