Packing can change old transactions (by deleting no longer used
Also note that a FileStorage contains back references (references
from one object record to a previous object record). Such
back references make it difficult to sticht together a backup
for transactions until a given tid and one for transaction from this
tid onward -- when some packing has happened in between.
