ResourceErorr => ResourceError

I am assuming this works out if request is a null pointer.

Maybe we should add an ASSERT(error) above this line to ensure that error is non-null?

Maybe we should give the parameter message in convertSoupErrorToResourceError() a default value of 0? Then we could remove the last argument in the call here.

The comment is sufficient as-is and I like how it's more concise that the old one. But something about this comment makes me feel that I'm missing some kind of reasoning into why we are calling didFinishLoading() now instead of calling it in callback closeCallback(). The old comment quasi-satisfied this "because"/or at least seemed to imply some kind of importance to this design decision with the sense of urgency implied in the last sentence. Maybe we should consider appending a "because" in the new comment.

How about: "We want to inform WebCore of load completion as soon as possible, so we do not wait for the stream to close." ?

This doesn't seem to add much of a reason compared to what you had previously. Maybe "We inform WebCore of load completion now instead of waiting for the input stream to close because the input stream is closed asynchronously."?

I've added:
ASSERT(error);
ASSERT(request);

Made this change.

I changed the comment to the one you suggested in your latest reply.
