I've gotten a bit lost in some of the diagnoses and experimental results and analyses and suggestions -- all of which I really appreciate! -- but I'm trying to get clear in my mind what the current state of things is from an application perspective. Is the following a fair characterization pending further developments? --- If you have a cons-intensive task then even if it can be divided into completely independent, long-running subtasks, there is currently no known way to get significant speedups by running the subtasks on multiple cores within a single Clojure process. In some cases you will be able to get significant speedups by separating the subtasks completely and running them in separate Clojure processes running on separate JVM instances. But the speedups will be lost (mostly, and you might even experience slowdowns) if you try to run them from within a single Clojure process. --- Or have I missed a currently-available work-around among the many suggestions? I realize that even if this is the current situation it might change via fixes on any one of several fronts (and I hope that it does!), but is this indeed the current situation?
