This isn't really what posix_fadvise() is intended for, I believe (or
rather, I can't figure out a way for us to be able to use it in that
manner). Check the posix_fadvise() discussion on -hackers for more
details.

Yes, I guess it should be "Better inform kernel on which pages to
cache".  Is that right?
