WiredTigerRecoveryUnit::setPrefetch() involves getting (or creating) a WiredTiger session which has an invariant that asserts that the WiredTigerSessionCache has not been shut down. However, this invariant is currently reachable since:
- The WiredTigerSessionCache is shut down not only during shuts down but also during replication rollback (here).
- WiredTigerRecoveryUnit::setPrefetch() is used by the validate command which is supported on secondaries so it can continue to run after the node becomes a secondary and starts doing rollback.
