Objects do not get deactivated mid-transaction, unless:
1. you explicitly deactivate one
2. you tickle the cache garbage collector. The cache will deactivate 
sufficient objects using its normal least-recently-used system.

Doing either of these has some disadvantages, which mvcc will completely 
eliminate. Im not sure if adding automatic mid-transaction cache management 
is on anyones roadmap yet.
