Comment (by tdammers):

 Sounds plausible. I managed to reproduce on GHC HEAD, and running on a
 machine with a HDD clearly shows excessive disk I/O. So my hypothesis so
 far has been that overly enthusiastic inlining might be the culprit, and
 if `{-# NOINLINE evaluate #-}` fixes it, then that would be consistent
 with that.
