I just fetched Clojure from SVN and restricted the heap size (both initial and max) to 256 MB, and your examples work for me: user> (count (pmap inc (range 1000000))) 1000000 user> (def result (map inc (range 1000000))) #'user/ result user> (count result) 1000000 user> (def result-p (pmap inc (range 1000000))) #'user/result- p user> (count result- p) 1000000 The last (count result-p) call takes a few seconds (probably because there's a one-to-one mapping of tasks to sequence elements) but it finishes.
