> The current implementation simply ignores late tuples without acking
> them, which causes timeouts and replays after
> TOPOLOGY_MESSAGE_TIMEOUT_SECS. A tuple which was late at a some time
> is going to be late at any moment in the future, so there is no point
> of replaying it, because the lingering late tuples will just block the
> topology (especially if TOPOLOGY_MAX_SPOUT_PENDING is set).
