> {{BufferedChecksumIndexInput}} implements {{Cloneable}}, yet its close method would return a shallow copy that still wraps the same {{IndexInput}} and {{Checksum}}. This is trappy, because reading on the clone would also read on the original instance and update the checksum.
> Since {{Checksum}} are not cloneable, I think {{ChecksumIndexInput.clone}} should just throw an UOE.
