I want to know more about this. How does it handle "unbalanced" CPU loads. For instance, one operation takes 30 seconds, and the rest all take 2. Also, how does it glean enough knowledge to know the "correct" number of threads for your block? Clojure has a really sexy pmap, preduce, etc. coming in 1.3 and after learning about how it actually I'm skeptical of this library and its effectiveness. How do these pmethods behave when they're thrown tasks which require variable lengths of time?
