You try to make a synchronous transaction. If not enough replicas are
alive, the transaction will timeout.

I also ask you to add a test on what happens, when quorum formula is
changed while there are waiting transactions in the limbo. For example,
if I set the formula to return a smaller value than the current number
of alive replicas, the transactions should get committed.
