FWIW, rebuilding ghc7 using ghc7 as the bootstrapping implementation
(and disabling the ghcquickbuild option, whatever that does) did give
me a sane ghc7 that is giving the expected speeds.  So, if anybody
feels like pointing fingers at anything I could be doing better in my
program, that's definitely welcome, but the regression part of my
problem is gone.
