> The METADATA table is often small, with many in-memory writes.  Because it is small,
it does not normally get flushed, which will prune data with the versioning/delete iterators.
 Over time, the many in-memory versions can cause poor performance.
> The file garbage collector (gc) will make lots of updates as it runs.  That would be
a perfect time to flush the table and prune the versions.
