+	    Fix some potential buggy behavior in how ticks are sent
+	    on inter node distribution connections. Tick is now sent
+	    to c-node even if there are unsent buffered data, as
+	    c-nodes need ticks in order to send reply ticks. The
+	    amount of sent data was calculated wrongly when ticks
+	    where suppressed due to unsent buffered data.</p>
