there are alot of choices. i'm succesfully using wrapper classes with
reference counting in my i/o streams library, for example. they are GC
roots, and they are freed in the same moment when their reference count
becomes zero.

class dtors should not throw any exceptions. stack-allocated struct
dtors can do what they want, just catch that and you'll got "nothrow"
function. what's the problem here?
