--- Max writes: I think it's probably best not to enable SAT with -O2 for the
--- 6.10 release. The version of SAT in HEAD at the moment doesn't incorporate
--- several improvements to the heuristics, and I'm concerned that without
--- those changes SAT will interfere with some attempts to write "high
--- performance Haskell", as we saw in some posts on Haskell-Cafe earlier
--- this year. In particular, the version in HEAD lacks the tail call
--- criterion, so many things that look like reasonable loops will be
--- turned into functions with extra (unneccesary) thunk creation.
