Summary: mmap missing offset parameter
Initial Comment:
For some reason, the author of the MMap module didn't see fit to
expose the "offset" parameter of the mmap syscall to python. It
would be really nice if it had that. Currently, it's always set to 0.
m_obj->data = mmap(NULL, map_size,
prot, flags,
fd, 0);

The patch just needs some attention (testing and possible
fixes) on Windows.

There's already a patch for this request:
http://www.python.org/sf/708374
add offset to mmap
The rationale is same.
It's almost ready to be committed but has been left out for a
year now. So give it a second chance.

I would, but I don't know the slightest about the C-level
mmap internals on any platform, and spending the last hour
looking through Python's mmap.c hasn't made me any more
informed.
James (or anyone else who reads this), are you able?

Would either of you care to provide a patch adding the
parameter? I'll review it...

I agree. Having access to the offset parameter would be
quite convenient, at least to some who use mmap in a
nontrivial fashion.
