This code runs inside Internet Explorer, not Chrome. Does it really require the
Hack() version that disables the thread io restrictions? Code in Chrome Frame
should not be subject to Chrome's thread io restrictions.

That's good to know that. I thought the thread io restrictions were effective
here. Remove Hack() suffix from here.

       upload_stream->Initialize(upload_data);
       upload_data_.Attach(upload_stream);
