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.
