monitor status across multiple reads?

[porjo]

For example a HTTP transfer done in chunks, using flowrate inside a http.RoundTripper:

func (t *limitTransport) RoundTrip(r *http.Request) (res *http.Response, err error) {
  body := flowrate.NewReader(r.Body, -1)
  r.Body = body
  // track  body.Monitor.Status() here
  return
}

(full source code can be seen here)

I'd like to keep track of the overall status of the transfer, however I find that Monitor gets flagged as not active at the end of the first roundtrip and so cannot be reused.

I've worked around this by commenting out defer.Done() in Reader.Close()
