But even with these refactorings the stats remain intact after calling
`reftable_writer_close()` or `reftable_writer_release()`, right? So it
basically continues to work as expected.
It might not be the cleanest way to handle this, but I think this patch
is an improvement over the previous state because we plug a memory leak
and deduplicate the cleanup logic. So I would suggest to defer your
proposed refactorings to a later point, if you're okay with that.
Thanks!
