It's especially strange since CURLE_UNSUPPORTED_PROTOCOL isn't an error that
can be returned by curl_multi_perform(). The enumerated set of errors that
are returned are the CURLMcode errors, NOT the CURLcode errors.

I suggest starting with an example program in docs/examples/ to see how the
multi parts all hang together.
