> DeletedColumn and RangeTombstone use the local-timestamp to update the digest during
repair.
> Even though its only a second-precision timestamp, I think it still causes some differences
in the merkle tree, therefore causing overrepair.
> I attached a patch on trunk that adds a modified updateDigest() to DeletedColumn, which
does not use the value field for its calculation.
