 Description   

The value of _shuttingDown decides the validity of oplogRecordStore pointer: when _shuttingDown is true, oplogRecordStore is very likely (there is a small window) to be destroyed. However, we don't have any mutex to protect _shuttingDown here. It's possible that _shuttingDown gets set to true while this expression is being evaluated.
