> The task should be finishable but isn't.
> That can be a problem when adding to wait queue and then rejecting the least
> important task (the one being submitted, or an old evicted one) - wait queue
> comparator takes finishable state into account, so while this task should be
> able to kick any non-finishable task out of the queue, it might actually get
> rejected because it "looks" non-finishable at submission time.
