Comment:
The [http://hackage.haskell.org/package/parallel new parallel package] on
Hackage fixes the space leak in this program (change `rnf` to `rdeepseq`
to compile it). I'm leaving the ticket open and moving it onto the 6.14.1
branch, because we still need to change the GC policy so that sparks are
not treated as GC roots.
