> Isn't this the very consequence of going async? Like I mentioned, depends on the language features. If it has coroutines/green threads/continuations, you can use async without unwinding the entire stack. CL will probably always have this problem, unless the bigger implementations independently decide to implement the necessary building blocks (which they probably won't). Try explaining that to me 5 years ago, though.
