> Batch requests using AsyncProcess get submitted to a thread pool. If the pool is too small or backing regionservers are overloaded, the pool may reject requests. Currently this causes a cache clear, which only exacerbates issues in most cases.
> If there's a real reason to clear cache, the individual failing tasks that actually get accepted into the pool should be enough to appropriately clear the cache. So let's special case REE in AsyncRequestFutureImpl to not clear cache.
