> We call Channel#size() inside the NIOFSIndexInput ctor but ignore the fact
> that it can throw an IOException. I ran into this due to a ClosedByInterrupt
> exception which we explicitly state don't support. This can also happen due
> to
> an IOException and we should at least not leak a file handle in such a case.
