Summary
The pooled Cache instance is conceptually moved to the root on complete or unwind. However currently we don't reset the reference back to null, instead relying on pushRootCachePool to update it when the next render begins/resumes. This PR explicitly sets the cache back to null and updates the comments to clarify that conceptually
popCacheRootPool()is moving ownership. This doesn't change much but maybe gives GC a chance to free the data a tad earlier.How did you test this change?
