The shootout could be a place to experiment with this, if we
could have one Erlang entry that assumes SMP, and one that
doesn't, for each benchmark (like we used to have a non-HiPE
and a HiPE version).

One issue is that there isn't e.g. a plists in the stdlib.
With permission from the shootout maintainers, we could
possibly have a patched build, with a lists module (etc.)
defaulting to parallel solutions (i.e. spawning processes
where sensible, and gathering results, preserving order
where necessary.)

Just a thought.
