:I think it is not as easy, because we want the current state to be the
:reference, and have the usage of the snapshots show what would be free'd
:when the snapshot was removed. So old, unmodfied data has to be charged
:to the current usage and not to the snapshot that first contained it.
That's actually very easy to do, because you extracting the information
based on the *DELETE* transaction id, not the *CREATE* transaction id.
If the information is not deleted (delete_tid is 0), then it is current
information regardless of how long ago it was created.
