Does anyone know what __write_ports_delfd() is meant to do? The block comment above write_ports claims it handles writes of the form "-<file descriptor>", which makes no sense (the file table of the writer has nothing to do with anything). It's called only when the character after the "-" is a digit, but the names it matches against (generated by svc_one_sock_name()) start with "ipv4" or "ipv6".
I suspect the comment above write_ports() is not correct. I assumed that delfd was symmetrical with addfd, but it isn't. More likely, addfd returns a string name that can be passed to write_ports (with a preceding '-') to terminate the socket.
