[Haskell-cafe] Shootout update

The shootout (sorry, Computer Language Benchmarks Game) recently updated 
to GHC 6.12.1, and many of the results got worse.  Isaac Gouy has added 
the +RTS -qg flag to partially fix it, but that turns off the parallel 
GC completely and we know that in most cases better results can be had 
by leaving it on.  We really need to tune the flags for these benchmarks 


It may be that we have to back off to +RTS -N3 in some cases to avoid 
the last-core problem (http://hackage.haskell.org/trac/ghc/ticket/3553), 
at least until 6.12.2.

Any volunteers with a quad-core to take a look at these programs and 
optimise them for 6.12.1?
