    Optionally you can specify a shutdown message `MSG`.
 
+   Also, you can specify optionally _rtt_ in milliseconds to automatically
+   shutdown the peer if round-trip-time becomes higher than defined.
+
+   Additional _count_ parameter is the number of keepalive messages to count
+   before shutdown the peer if round-trip-time becomes higher than defined.
