> OakDirectory has to at times perform directory listing specially at the time
> of opening of index. With DocumentNodeStore such listing of child nodes
> "might" be slow if there are lots more deleted nodes and GC has not cleared
> them so far (due to OAK-1557).
> As seen in OAK-2808 Lucene might be creating and deleting lot more files. To
> speed up such lookup one OakDirectory can save the listing of child nodes as
> an array property once the writer is closed.
