Commit message is too light on this one. Why does this need to be
stored? Isn't the cost of rebuilding this in-core cheap?
Adding this chunk on disk in my opinion only adds more burden. Now you
have to verify that these offsets actually point to the right place.
This is a very good point. I'll drop the chunk and just read the names
directly to construct the array of strings.
Thanks,
