As ever I am jumping in without reading the code, but in general unless
the tidydb process is rewriting the db (ie reading old file, writing
relevant bits into new file), there will be no block reclamation here, so
unless you truncate the overall length of the file (in which case you
reclaim the final set of blocks).
I guess over time the file would tend to fill in as the keyspace is used
up..
