You might also want to look at Atila Neves's automem package. It 
uses atomic increment/decrement when the type being 
reference-counted is `shared`.

That RefCounted only counts on stack, it can't be put in shared 
storage.

 storage.

There are some bugs with shared at the moment in dmd (I 
introduced a bug fixing a different bug and now I'm trying to 
figure out what the best way out of this mess is), so what I'm 
saying might not compile right now but should:

auto ptr = new shared RefCounted!(...);

If you rely only on postblit, then you can't concurrently read 
and write to refcounted shared storage without additional mutex 
lock, so it should be at least a non-copyable container (similar 
to what rust does).
