how can see number of rollbacks in stm in clojure?

you can't... unless willing cheat:

(defmacro spy-dosync [& body]   `(let [retries# (atom -1)          result# (dosync                    (swap! retries# inc)                    ~@body)]      (println "retries count:" @retries#)      result#))

and replace dosync spy-dosync.
