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.
