Lisp (what is a Common Lisp "flavor"? Racket is Scheme) has answers to all... Of course the benefit of Clojure baking those things in is you can rely on them in other people's programs, but still idiomatic Lisp seems to do an ok job managing state, especially compared to other languages. Plus its other features that Clojure lacks might make the tradeoff worth it.
