While on that topic, it'd be nice to see a fixed-size ArrayBuffer,
for working with streams and large-files.

Currently: blob requires the entire file be downloaded before use,
classically, the stream could be ready while downloading, and the final
response just 'tossed' (when the stream is complete).

Even a hard-coded array buffer size would be helpful (though it'd be 
nice to have that as a settable value):

Something along these lines would allow processing of binary data 
without requiring
the entire stream to be loaded into memory / downloaded.

xhr.buffer = new ArrayBuffer(...len...);
