If you have a working select(), it will tell you the sockets on which read()
and write() won't block, so non-blocking reads and writes are not necessary.
On Windows, sockets, pipes, and files are each completely distinct types
with their own functions and unifying them under one select()-like interface
requires faking it using threads behind-the-scenes AFAIK. Personally, I'd
be happy with continuing to only support socket objects on Windows.
