Not sure if replying to yourself is good form, but I have an important
development: I forced it to register for both CURL_POLL_IN and
CURL_POLL_OUT on all sockets, and the upload worked perfectly on the
first try. So it does appear that libcurl is requesting the incorrect
type when registering the data socket, for whatever reason.
