Another option is to have a process periodically/permanently verify the
integrity and remove records which are not referenced. This means you
eventually get consistent even if something goes wrong at some point. Of
course, it open up a can of worms in the sense that you may have new
correctness problems, but the upshot is that you can sometimes also use
this in a more distributed setting.
