bq. still need to do something to prune the listings and to delete files no longer referenced

That you can do in AsyncIndexUpdate cycle itself say after every 10 cycle/2 hrs

> Currently if the OakDirectory finds that a file is missing or in some way damaged, and
exception is thrown which impacts all queries using that index, at times making the index
unavailable. This improvement aims to make the OakDirectory recover to a previously ok state
by storing which files were involved in previous states, and giving the code some way of checking
if they are valid.
