Presumably it detects duplicates by checking the XID (transaction ID)
field of the request.

(For those who are curious, "dg" in the TIRPC version presumably stands
for "datagram"; TI, you see, stands for "transport-independent", so UDP
isn't the only datagram transport - I think it's been run atop the ISO
connectionless transport protocol as well, for example.)
