    evl/proxy: enable fixed-size write, polling for output to drain · 9332f2a3

    Connecting a proxy with some special file may impose fixed-size writes

      transfer buffer to complete the sending, unless O_NONBLOCK is set on
      the proxy file.
    - POLLOUT|POLLWRNORM can be monitored for waiting for the output to
