the notion of isolation is also not hard compliant. at least till multi 
versioning concurrency control jaunx happens.

ie thread a should not see results from thread b commit that happened after 
thread a started its transaction.

there is a loose form of consistency in that all objects must be pickling and 
reachability requirements, but you're right consistency must be enforced at 
the application level.

cheers
