Hi Sean, you misunderstud my context. I do not talk about result of cloning but about implementation of clone process by FB developers. When i talk about copying data i talk about transaction data like flags, tip ... not database data like records...

Is this a problem or is simple to clone > transaction in atomic way? Given that the clone would have the details of an **active** transaction, it would be isolated from any other transactions just as the active transaction would be. Read-committed/snapshot transactions only see data for transactions which were committed before the new transaction started, changes from any commit after that are not seen. So, there is no issue.
