Nor would one expect it to need to, unless one were using "burst mode" 
to have more than one transaction inflight at one time.

And unless one uses the test-specific -e option to provide a very crude 
retransmission mechanism based on a socket read timeout, neither does 
UDP_RR recover from lost datagrams.
