--------------------------------------------
This seems to be caused by https://asterix-gerrit.ics.uci.edu/#/c/1773/
> AppendOnlyLinkedMetadataPageManager.put() is called after close(). HYR0012 is
> thrown

> So AppendOnlyLinkedMetadataPageManager.close() is called from LSMHarness:502
> (flush), then the next line (LSMHarness:503) calls the callback which tries
> to write data into the closed page manager. At that point its
> 'confiscatedPage' is 'null' and therefore HYR0012 is thrown
