Nhat Nguyen 1ef87c9a68 Refresh should not acquire readLock (#48414) ... Today, we hold the engine readLock while refreshing. Although this choice simplifies the correctness reasoning, it can block IndexShard from closing if warming an external reader takes time. The current implementation of refresh does not need to hold readLock as ReferenceManager can handle errors correctly if the engine is closed in midway. This PR is a prerequisite that we need to solve #47186.		2019-10-25 17:32:35 -04:00
