See: http://clojure.org/transients
"...Note in particular that transients are not designed to be bashed
in-place. You must capture and use the return value in the next call."
Also consider using "assoc!" and recursion:
(defn test []
(loop [transient-map (transient {})
i 0]
(if (< i 100)
(recur (assoc! transient-map i (str i)) (inc i))
(persistent! transient-map))))
