Well, it's not disk IO, it's network IO. I figure if you set that
flag you should expect commensurate error return values. This is
conceivably a useful behavior, and POSIX does not forbid it, so I just
made the judgement call to not deny the functionality.
Would you actually be surprised to get EAGAIN if you requested
non-blocking access to a file stream, ignoring the fact that it just
happens to not have been done already for other S_ISREG file streams?
