I think you didn't quite get, but reviving the runtime Sebastian 
done is way more critical than having the GC, and it is as he 
said, having a new backend is a far away dream, we should not 
jump steps. If the runtime is not revived, there is no point in 
having a GC at all, and it is impossible to use the GC without 
the runtime, but runtime without the GC, it is possible :)
