You can not just discard the oldest data of a long-running execution trace when doing replay-based time-travel debugging.

You can not replay execution without a known state followed by all non-determinism after that state which is most easily done by starting from the initial state. To discard data, you need to manifest a state snapshot corresponding to that time to enable forward reconstruction from that state.

you're right: in the RR case: currently this is not merged yet, but a RR contributor works on persistent checkpoints; they can act as snapshots
