> Behavior of delete* calls in DataStore is insufficiently defined. Some unit tests in DataStoreUtil seem to indicate that after a successful call to delete the subsequent queries should not return deleted items. Other tests indicate that an additional DataStore.flush() call is needed.
> If we could rely on the latter assumption this would allow for some important optimizations in the implementations of DataStore - bulk updates that are visible only after an update transaction is finished are usually much less expensive to perform than equivalent multiple item by item transactions.
> Therefore I propose to strengthen the meaning of delete* calls, so that their effects are guaranteed to be visible to get/execute ONLY after a subsequent flush() call.
