Re: [PATCH 00/23] Prepare to separate out a packed_ref_store

This patch series is the next leg on a journey towards reading
`packed-refs` using `mmap()`, the most interesting aspect of which is
that we will often be able to avoid having to read the whole
`packed-refs` file if we only need a subset of references.

Which features of mmap() are you going to use? We have only MAP_PRIVATE on Windows. We do emulate PROT_WRITE (without PROT_READ), but I don't think that code is exercised anywhere. See also compat/win32mmap.c.
