[~davidzchen], are you going to continue to own this, or should someone else take it over?

> After SAMZA-123, the checkpoint log has a new format (keyed entries interspersed with statelog-partition mapping) and a new name.  It would be simple to write a tool that would consume an old-style log and write out a new-style log, using the GroupByPartition strategy.  This would allow existing jobs to not lose checkpointing.
