I have simplified the long-time living netlink listener more by

As I wrote in another message, there is basically no benefit in doing
that, because it forces the handler to be netlink-aware.
But then it would still need to be micro-protocol-aware. The netlink
protocol is nearly identical to the micro-protocol you proposed earlier;
maybe being netlink-aware isn't so bad?
The main difference is whether it uses recv() expecting a datagram or
read() and has to parse some message framing. I'd bet the first
requires less code. And, it doesn't have to be a netlink socket; the
messages could be relayed through any datagram socket.
