Postponing FD_CLOSE until all data has been read out may be a good idea,
I'm just not sure whether that's what Windows does.

Don't think so, unconnected datagram sockets should preferably work too.
(I also think poll() may be prettier than MSG_PEEK.)
If we do it Alexandre's way, perhaps we could add an explicit poll() call
in sock_reselect, it'd still return POLLIN | POLLHUP when there's data,
and so it could just call sock_poll_event() with that...
