The reflect.Value.Interface method shallow copies the underlying value, which may copy mutexes and atomically-accessed fields. Some usages of the Interface method is only to check if the interface value implements an interface. In which case the shallow copy was unnecessary. Change those usages to use the reflect.Value.Implements method instead. Fixes #838
