Possibly I'm missing something here, but I was under the impression that
to _really_ utilize a dual core system you need to use Jackdmp.
Jackd will only use one core. The other core won't be without work
though, there's plenty of work to redraw gui's and what not.
Someone do correct me if I'm wrong.
