But a "status change" for a reading Socket is "stuff can now

waiting to be read" which I'd hoped for, since my program (IRC
bot) in essence connects once and stays such throughout its
life.
What else is there to select that I'm missing? Or is it mostly
a thing for programs with lots of Sockets, lots of connections?
The read set is used to determine if a socket has data waiting to
read. It just happens that with a listening socket, that means
there's a new connection. With a normal socket, it means data
packets are ready. Maybe you should take a look at the classic
Beej's guide, which covers the C API. Should be easy to translate
to the std.socket API.
