Review comment:
Right, if after `invokeFinishBundle()` has been called the cleanup queue is
always cleared as part of however many additional bundles, then we are fine. If
we delay any cleanup for after the checkpoint has completed, then we would have
a problem.

> Cleanup timers and user timers are fired at the watermark. Processing of
> timers in the SDK worker is asynchronous, so it is possible that the state is
> already removed when the user timer callback executes.
