  Make sure the TTY has not disappeared out from under us before calling
  ttydevsw_outwakeup().  This should fix panics which occur after remote
  login sessions timeout during moderate TTY activity.  An example of
  where this might occur is where a pending write to the terminal is
  occurring while sshd(8) is shutting down the TTY after a TCP timeout.
