> this creates a base_x directory (for insert-only transactional tables currently and for
full CRUD once 'rename' in the MoveTask is eliminated) but subsequent read fails with "Not
enough history available for..." error.
> The problem is that the logic to produce this exception finds this base_x but treats
it as if it was produced by a compactor, in which case the error would'v been appropriate.
