I believe that we can utilize nearXidVersion for this ordering (or some
sort of it's modification). Since cache version contains local order,
topology version and node ID and also is comparable, it is guaranteed that
nearXidVersion is always unique and there is always an unambiguous order
between any two Xid versions.
