[Haskell-cafe] Help with "shootout"

Hello all, I decided to put together an entry for one of the shooutout categories: http://haskell.org/hawiki/ChameneosEntry It involves 4 threads. There is no current Haskell entry. Anyone have comments? Alterations? I can't have created the best code yet. I don't have the compilers for the other entries, so I can't compare speed on my powerbook (which is the wrong kind of CPU anyway -- they test on an AMD system). -- Chris
