> Currently compaction will be skipped if some rough estimation determines that
> there is not enough memory to run. That estimation however assumes that each
> compaction cycle requires as much space as the compaction map already takes
> up. This is too conservative. Instead the amount of memory taken up by the
> last compaction cycle should be a better estimate.
