That sounds pretty ugly. Perhaps better is a "cycle ID" field added to
the table entries, assigned from a counter that's bumped before entering
the fsync loop. Then you could distinguish entries made before starting
the loop from those made after. One fine point is to not let
AbsorbFsyncRequest change the cycle ID on a pre-existing entry ...
