> WindowsFs has some race conditions when files are concurrently opened and
> deleted. A file might be successfully opened while concurrently deleted which
> should be prevented by the WindowsFS with an IOException / access denied. The
> problem is that we try to remove the leaked file handle form the internal map
> on close which fails since we fail to read the key from the filesystem since
> it has already been deleted. This manifests in subsequent `access denied`
> exceptions even though all streams on the file are closed.
