Well, since the source for _read_chunked includes the comment

        # XXX This accumulates chunks by repeated string concatenation,
        # which is not efficient as the number or size of chunks gets big.

you might gain some speed improvement with minimal effort by gathering
the read data chunks into a list and then returning "".join(chunks) at
the end.
