Review Comment:
I think we could do better simplification around booleans here and get rid
of the hasRemainingWork helper, and some unneccessary comments:
```
private void handleWorkerExit() {
boolean isLastWorker = activeWorkers.decrementAndGet() == 0;
boolean hasWorkLeft =
!planTasks.isEmpty() || !initialFileScanTasks.isEmpty();
boolean isShuttingDown = shutdown.get();
if (isLastWorker && (!hasWorkLeft || isShuttingDown)) {
signalCompletion();
} else if (isLastWorker && hasWorkLeft) {
shutdown.set(true);
failure.compareAndSet(
null,
new IllegalStateException("Workers have exited but there is still
work to be done"));
}
}
```
