I did?  Not that I recall, though I might have done so.  Compacting is
of questionable value.  A compacted database will allow the fastest
possible scoring since there's a minimum amount of data to read.  On
the other hand, writing will be slower since a maximum number of
data blocks will need to be written as splitting occurs to accommodate
new tokens.  Which is more important?  I don't know.

Doesn't matter. :-)
