 Description   

double_rollback.js and double_rollback_early.js test that rollback via refetch does not corrupt data due to double rollback scenarios. It would be good to make an analogous test for rollback to a stable timestamp to show that it is in fact recoverable. This would do a double rollback and show that no "minValid" is required post rollback to do another rollback.

We're marking this as optional since jepsen should give us coverage, albeit less reproducibly.
