TSAN identified a data race between updates to the states_ map (ex. in Mock::UnregisterLocked) and the iteration done in this destructor. Writes to the map use g_gmock_mutex, but the destructor does not acquire it. Acquiring the lock here fixes the data race. It should only be possible to trigger this TSAN finding in cases where a mock object is deleted by a thread other than the main thread.
