Ok that works on the samples. Generally speaking though if a status !=
CURLE_OK is passed to a done handler is it possible for that done
handler to return a result of CURLE_OK? I'm trying to figure out if
there will still be a scenario where Curl_pgrsDone() could be called
with a bad status and whether or not it's permissible in that case.
