> We started to distinguish what's loaded to heap, and what's not from
> Statistics.db. For now, ancestors are loaded as they needed.
> Current serialization format is so adhoc that adding new metadata that are
> not permanently hold onto memory is somewhat difficult and messy. I propose
> to change serialization format so that a group of stats can be loaded as
> needed.
