I have committed this after extensive revisions. I removed the
sync_files count, since no one ever explained what that was good for.
I renamed a bunch of things so that it was clear that these stats were
referring to checkpoints rather than anything else. I moved the
documentation to what I believe to be the correct place. I fixed a
few other assorted things, too, and reverted a couple hunks that
didn't seem to me to be adding anything.
