| | | | | | | | | | | | | | | We don't want floating unlinked executable CUs. They should always be tied to an engine, and the engine should not change. This gives us one definite point where to register them with the engine (to be done in subsequent change). Unfortunately, due to the refcounting, we need to remove the engine from any still-referenced CUs when the engine itself is destructed. We will be able to drop the refcounting and make the engine fully own its executable CUs once we can hold base CUs in most places.
