Looks good. But why did you not yet wire the BarrierTracker, i.e. provide a
user setting so that it can actually be enabled?

> We need to make the Checkpoint handling pluggable, to allow us to use
> different implementations:
> - BarrierBuffer for "exactly once" processing. This inevitably introduces a
> bit of latency.
> - BarrierTracker for "at least once" processing, with no added latency.
