> ViewFileSystem.close() does nothing but remove itself from FileSystem.CACHE.
> It's children filesystems are cached in FileSystem.CACHE and shared by all
> the ViewFileSystem instances. We could't simply close all the children
> filesystems because it will break the semantic of FileSystem.newInstance().
> We might add an inner cache to ViewFileSystem, let it cache all the children
> filesystems. The children filesystems are not shared any more. When
> ViewFileSystem is closed we close all the children filesystems in the inner
> cache. The ViewFileSystem is still cached by FileSystem.CACHE so there won't
> be too many FileSystem instances.
> The FileSystem.CACHE caches the ViewFileSysem instance and the other
> instances(the children filesystems) are cached in the inner cache.
