For Py3k, I would like to suggest a buffer protocol modelled after iovec structure that is used by the readv system call. On many systems readv is more efficient than repeated calls to read and I think Py3k will benefit from a direct access to that feature.

-1. It's difficult to use, and I question that there is any benefit. I believe readv is there primarily for symmetry with writev and hasn't any sensible uses on its own. writev is there so you can add additional headers/trailers around data blocks you received from higher layers. I even doubt that exposing writev in Python would make a measurable performance difference.
