Right, I just checked the linux kernel source. It's even a bit worse,
only root can do TIOCCONS on linux:

    static int tioccons(struct file *file)
    {
            if (!capable(CAP_SYS_ADMIN))
                    return -EPERM;

The way it is done in other UNIXes makes much more sense, see e.g.
the SRIOCSREDIR ioctl in solaris.

Cheers,
  Michael.
