infinite recursion bug of the old example (and actually compiles, the old
example had a lot of typos).

ppapi/examples/url_loader/streaming.cc:13: // Stream-to-file is simpler, but
won't allow you to get partial data as it
This is not exactly true.  You can open the file for reading, and read from it,
while the download is still underway.  At least that was what I had in mind when
I created the API.

It might help to say:  "we reached the end of the stream (result == 0) or..."

document.addEventListener("DOMContentLoaded", AddListener, false);
note:  you could also just put this <script> block at the end of the document
(or at least after the <object> tag).  then you wouldn't need to register for
the DOMContentLoaded event.
