Comment:

 I've had a look at `fannkuchredux` and I can't see any slow down, either
 non-threaded or threaded `-N4`.

 If you still think there's a regression, can you please give complete
 reproduction instructions (i.e. the code being compiled, the compilation
 commandline, and the command used to run the program), the platform you're
 on, and the figures you're getting.

 Thanks!

 A couple of the measurement differences to GHC 7.0.1 look strange, just
 letting you know.
