Here is another detail that I would like to see addressed. 
The new API does not seem to provide for a way to read
data directly into an existing object without creating
an intermediate bytes object.

Python 2.x has an undocumented readinto method that
allows to read data directly into an object that supports
buffer protocol.

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.
