hmm, the resource being provided to the background thread is really the 'data'.
It is about suppressing WebURLLoaderClient::didReceiveData in favor of
WebThreadedResourceBackgroundClient::didReceiveData. On that note, I wonder if
we shouldn't use the term "data" in place of "resource"?

it would be helpful to document the API better. it is not clear when one is
supposed to call createThreadedResourceProvider relative to other methods on
WebURLLoader.
