I see so it's really not about exceptions but rather the managed types in general.

The manual says it makes all functions slower, 5-10%?? Does that apply to all functions or just ones with managed types in them? It's also curious why the try..finally block would have the kind of impact, all it does is call finalize functions on managed types right?
