    sys/kern             tty_tty.c 
  Log:
  If /dev/tty gets opened after your controlling terminal has been revoked
  you can't call tty_clone afterwords. OpenBSD and NetBSD both fail the
  open call in that case, so we should do so as well. This can
  be done in ctty_clone by returning with *dev==NULL. Admittedly this
  causes open to return ENOENT, instead of ENXIO as on the other BSDs,
  but this way requires the least touching of code.
