A good portion of our mock interfaces are used to make unit testing easier. The LockerNoop::isW() method was changed to always return true, as an example. However, the LockerNoop is used outside of unit tests. Returning true that the global exclusive lock is held by multiple operations can result in bugs as seen in ~~SERVER-59591~~.
