  - ReplicationStorageIT: Wait for all pushes without order
    
    Some tests don't have a predefined order for which events will be
    replicated first. Using a timeout based on a single replication event is
    flawed when we don't know the expected order. Instead, use a timeout for
    the group of events and ignore the order.
    
    For two events replicating to a single remote with a single thread, we
    expect the complete replication to take twice as long. Two events
    replicating to two remotes will use one thread each and therefore not
    take any longer than the single remote case.
