I thought we avoided flushing them to disk on checkpoint, or did
that idea fall flat?  Does the background writer flush them?  If
neither of these happens, then we can legitimately call them
in-memory, as long as we point out that they are saved on a clean
shutdown for reload on startup, and may be flushed from RAM at times
when other objects need the memory.
