    process: Handle EWOULDBLOCK in socket connect
    
    Now that we set a timeout for the socket, it can return EWOULDBLOCK
    if a signal or other event happens to wake up even if we don't timeout.
    
    If this happens, retry the connection, else we simply see it quickly
    loop through the retries and abort the connection in a very short
    interval.
