> Seems there is an issue with committing/rolling back transactions on topology
> changes because we expect all transactions holding topology locks to be
> finished at this time. Mvcc updates lock topology and produce remote txs at
> once, in other words existence of active remote txs implies pending updates
> and locked topology which cannot be true because of being finished exchange
> (all old txs are finished, all new txs are waiting for topology).
> Need to be investigated.
