- Able to send UDP packets before interface is configured.
- Able to use any net.PacketConn.
- RFC2131-compliant retransmission logic.
- Tests.
- Race-condition-averse.
Previous clients (both mine and the ones here) are prone to race
condition errors.
Having one and only one place that calls receive on the socket
"continuously" without having to coordinate hand-offs makes the logic
way easier to follow, and allows for multiple requests in flux at a
time.
