It may turn out that this is actually a bug in merging, where old
segments are not getting deleted.  I noticed in the optimized index that
there is a single large segment of about 20GB and a bunch of other
segments that are all older than the single large segment.  I'm manually
optimizing that index again to see what happens.  I'll probably need do
the rebuild again with infoStream enabled.
