> 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.
