      Note that a sync is still needed to flush dirty cached data prior
      to acquiring a timestamp for the 'snapshot' to be set in stone.
      (dirty data cached in-memory has no historical tags and must be
      committed to physical disk before it can be accessed historically).

Wouldn't making timestamp queries (at least from userland) enforce a sync on the volume in question be useful here?
