Hi Duncan, I'm following the story regarding (parallel) GC in this example with interest, but forgive me if I ask a more minor question regarding your modification of an extra parameter, "n", to "heavytask". Does this really help (to ensure that each core does work independently)? Surely, with fibs now described in a where clause, the "0:1:etc." form would not be shared among the (8) instantiations of "heavytask"?
> heavytask m n = putMVar m $! (fibs !! 100000) > where > fibs = n : (n+1) : zipWith (+) fibs (tail fibs) Regards, Paul
