 /**
  * This method is invoked when the idle timeout triggers. We check the close state to act
  * appropriately:
  *
  * <p>* NOT_CLOSED: it's a real idle timeout, we just initiate a close, see {@link #close(int,
  * String, Callback)}.
  *
  * <p>* LOCALLY_CLOSED: we have sent a GO_AWAY and only shutdown the output, but the other peer
  * did not close the connection so we never received the TCP FIN, and therefore we terminate.
  *
  * <p>* REMOTELY_CLOSED: the other peer sent us a GO_AWAY, we should have queued a disconnect, but
  * for some reason it was not processed (for example, queue was stuck because of TCP congestion),
  * therefore we terminate. See {@link #onGoAway(GoAwayFrame)}.
  *
  * @return true if the session should be closed, false otherwise
  * @see #onGoAway(GoAwayFrame)
  * @see #close(int, String, Callback)
