Versions are nothing else than long running transactions (which the
additional but not essential feature to be able to join such a transaction).

Locking might be necessary for long running transactions as
the longer the transaction the higher becomes the risk of
conflicts and the more costly a redo of the transaction.

When we get long running transactions I will be happy to
let Versions alone.
