--- Comment #3 from Behdad Esfahbod <freedesktop at behdad.org> ---
I'm concerned about this.  Note that MAP_PRIVATE doesn't do what you think it
does.  Quoting manpage:

       MAP_PRIVATE
                  Create a private copy-on-write mapping.  Updates to the map‐
                  ping are not visible to other  processes  mapping  the  same
                  file,  and  are  not carried through to the underlying file.
                  It is unspecified whether changes made to the file after the
                  mmap() call are visible in the mapped region.

The last sentence is important here.  No?
