[New-bugs-announce] [issue8042] mmap buffer implementation does not respect seek pos

New submission from Matt Gattis <gattis at gmail.com>:

If you do:

import io,mmap

b = io.BytesIO("abc")
m = mmap.mmap(-1,10)
m.seek(5)
b.readinto(m)

M is now:
'abc\x00\x00\x00\x00\x00\x00\x00'

Basically there is no way to readinto/recv_into an arbitary position in an mmap object without creating a middle-man string.
