Comment(by simonmar):
I looked into this a bit today. One problem is that now GHCi is
dynamically linked, we always retain all CAFs (because we set `keepCAFs`
to true). This means that any loop that goes through a CAF won't be
detected as a black hole, because the CAF is inherently live.
I suspect this isn't the only reason that we don't get blackhole
exceptions in GHC, though.
