Ah. Well we could do that in Clojure without dealing with Python, and our tests show that we'd get the multicore speedups that we want. But I'm not eager to re-engineer everything to launch and use and deal with multiple JVM instances and the necessary intercommunication. I'd like to use the built-in Clojure concurrency support, which is elegant but isn't giving us reasonable multicore utilization.
