In the Hurd, nothing implicitly changes what your controlling tty is.
Only TIOCSCTTY does that (see libc/hurd/hurdioctl.c).
However, any fd you receive in any fashion might be an fd to your
controlling tty, so you have to discover and then treat it as such.
_hurd_intern_fd takes care of this for you.
Thanks,
Roland
