> Scenario:
> tx1 writes to k, hash(k) = {A, B}. Tx is prepared, commit hasn't been send yet.
> New node C has joined so that ch(k) = {C, B}, tx1 hasn't completed.
> tx2 writes on k adn prepares/acquire lock on k at C.
> both transactions commit at the same time resulting in B seeing tx2 result and B seeing tx1 result.
