<pre>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?</pre>
