> Reading checkpoint meta data and finding key-groups in restores sometimes
> require to seek in input streams. Currently, we always use a seek, even for
> small position changes. As small true seeks are far more expensive than small
> reads/skips, we should just skip over small gaps instead of performing the
> seek.
