Why do you need to do this? It might be more effective to allow 
multiple GC's.

but surely you can set the GC of the dll to use that of the 
another. You will need to expose a method to set the GC from the 
dll..

void SetGC(GC gc);

type of thing...

Where GC is info regarding the GC to do so which I don't know 
much about. The latest dmd supports hooking ones own GC so it 
might be just a matter of using those functions to point to the 
correct gc.
