>             Project: Hibernate ORM
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 4.1.1

> Implicit flushes in my opinion always should be, as widest as possible, under users control, this because
> unneccessary flushings often create serious implications, especially when working with long-time transactions.
> On long-time transactions the time-window between flush and final commit become big enough
> to cause lock-waits or/and lock-timeouts on concurrent transactions.
> With bugfix HHH-7094 the NaturalIdLoadAccess becomes pratically ununseable for our projects.
> Like on all Hibernate Query-Apis, the user should have the possibility to choose between variuos FlushModes.
> Example:
> (Simple)NaturalIdLoadAccess naturalIdAccess = session.by(Simple)NaturalId(MyEntity.class);
> naturalIdAccess.setFlushMode(FlushMode.AUTO); // flush if required
> naturalIdAccess.setFlushMode(FlushMode.COMMIT); // don't flush until commit time
> Object obj = naturalIdAccess.load(id);
> N.B.: I enabled the 'Requires Release Note' check-box, because this enhancement implies a behaviour change.
