2185,Memory leak with parMap,igloo,simonmar,"With the attached `All.hs`, if you run the program without any arguments (so that it uses `parMap rnf` in `gen_blocks_list`) then its memory usage keeps going up, even though at the top level it's just running the same computation 5 times in a row. Memory usage goes up to over 100M.

If you give an argument (any argument, so that it uses `map` instead) then memory usage is constant and only a few megs.

Happens in 6.8.2 and the HEAD.
