Interesting. non-exact GC but with about the same performance.The bad part for D would be, that this GC collects periodically, so even if you don't use GC'ed memory it will be invoked :-/ On the other hand it stops the world more often, but only for much shorter time - at least in interactive programms a better choice I think.
