Ah I see.  Well, Linux builds in Debian include separate smp and non-smp images.
I guess we'll have to do the same when we release, but personaly I wouldn't
bother for now.

But the ioctl in openpty() is TIOCSWINSZ instead, and "Resouce temporarily
unavailable" is EAGAIN IIRC, not EINVAL.

TIOCSCTTY is, however, found in login_tty().  I don't see why the ioctl fails,
but there's fallback code below.  What happens if you do:
