    libfetch: Use select(2) as a consequence of switching to non-blocking
    
    Since the socket is non-blocking, it is necessary to use select(2) even
    when there is no timeout, because read(2) will return immediately if there
    is no data waiting in the TCP buffer, causing fetch_read() to busy-loop on
    slow connections.
