+This will limit the number of queries sent over a connection before
+triggering a re-connection. Once re-connected it will reset the counter and
+continue sending queries until the limit is reached again, triggering
+another re-connection and so on.
+Using this option will also enable counting number of responses received
+for each connection and once the limit is reached for sending queries it
+will wait until the same amount of responses has been received before
+re-connecting.
+Waiting for responses may timeout and the timeout used for this is the
+same as specified by \fB-t\fR.
+Note that this option is only useful for connection oriented protocols.
