I think "zone btree" of the following should be "zone freemap" since this whole L1/L2 iteration of 8MB chunks deals with freemap zone, but not disk space for btree zone.

I git blamed to find where this commit was made which was da44aa75 in 2008. From what has been #if0-ed, it seems to me "btree" literal should be "freemap".
