FWIW I can confirm the following code produces {:a 90} consistently:
(let [v (transient {:a 0})
f1 (delay (reduce #(assoc! % :a (+ (:a %) %2)) v (range 10)))
f2 (delay (reduce #(assoc! % :a (+ (:a %) %2)) v (range 10)))]
@f1 @f2 ; wait for futures
(persistent! @f1))
Note that there are no future calls here. Clojure 1.5.1
Part of me wants the result to be {:a 45}
