You cannot have incremental collection as that requires barriers 
and there is no way in D to tell whether you should or should not 
emit costly barriers statically during code gen. D would need to 
add an actor concept to get there.

So that means there are only three options left: single threaded 
GC pool, non-language GC or ARC.
