What's changed and what's your intention?
Previously, without sequence-based operator cache eviction, the memory manager needed to wait for barrier completions to update eviction info. However, it doesn't need that now.
We can decouple the memory manager tick interval with the barrier interval, to achieve more efficient operator cache eviction even when the barrier interval is high.
