They are not. By subsequent calls of the published method "stamp",
the single timestamp object in the container is overridden by
a newly created one. 

However, all timestamps are added to the BoboPOS db on disk.
This is also as expected, because the db is a multiple revision db.

My problem is that after a pack operation on the BoboPOS db, the 
non-current timestamps are *still* present in the db, even though 
they don't seem to be reachable from the root Container object. 
As a result, the db keeps growing, while I would expect it to 
have a constant size (after a pack).
