UDP is unreliable even over Ethernet or other ``perfect''* networks
(at least in 4.2BSD) because since it doesn't have windowing (flow
control) so packets can and do get dropped after being successfully
received, checksummed, etc.  (Take a look at sbappendaddr.)

*Anyone who's used marginal hardware knows there's no such thing as
a perfect network. . . .
