Re: ACIDity of Prevayler 2.6

I think the same way. Klaus, IMHO you're just pushing definitions.
principal is simple: if transaction fails roll it back.

* in java a failure means exception
* if prevayler can rollback an exception in a transaction than it's atomic
* who throwed the exception, is it a human or whatever error is unrelevant

I'm not against the change, it's a matter of design choice. Personally I
would make it non default and document properly how it changes atomicity
property at what cost. And maybe change the name from food taster to some
atomicity bla bla thing.

my 2 cents
