> There's a shortcut in compaction selection that causes the selection of expired store files to quickly delete.
> However, there's also the code that ensures we write at least one file to preserve seqnum. This new empty file is "expired", because it has no data, presumably.
> So it's collected again, etc.
> This affects 94, probably also 96.
