Thanks for the tip. By coincidence, I just stumbled across ExecutorService 
yesterday via the example at http://clojure.org/concurrent_programming. I'm 
never thrilled about having to use Java APIs directly, but in this case an 
ExecutorService does what I want much better than pmap, and isn't too difficult 
to use.
