And how can I seek the raw file to zero?
Using buffer.raw.seek(0), buffer.tell() becomes inconsistent:
$ ./python
Python 3.2.1b1 (3.2:bd5e4d8c8080, May 15 2011, 10:22:54)
>>> buffer=open('setup.py', 'rb')
>>> buffer.read(1)
>>> buffer.tell()
1
>>> buffer.raw.tell()
4096
>>> buffer.raw.seek(0)
0
>>> buffer.raw.tell()
0
>>> buffer.tell()
-4095
Same problem with os.lseek():
$ ./python
Python 3.2.1b1 (3.2:bd5e4d8c8080, May 15 2011, 10:22:54)
>>> import os
>>> buffer=open("setup.py", "rb")
>>> buffer.read(1)
>>> os.lseek(buffer.fileno(), 0, 0)
0
>>> buffer.raw.tell()
0
>>> buffer.tell()
-4095
