(state State, err error)

// setState sets and broadcasts the provided state if it is greater than the
// current state and the error if one has not already been set.
func (s *ptyState) setState(state State, err error) {
	s.cond.L.Lock()
	defer s.cond.L.Unlock()
	// Cannot regress states.  For example, trying to close after the process is
	// done should leave us in the done state and not the closing state.
	if state <= s.state {
		return
	}
	s.error = err
	s.state = state
	s.cond.Broadcast()
}

// waitForState blocks until the state or a greater one is reached.
