Using scala actor framework as fork-join computation?

Is it possible, in theory, to use the Scala Actor Framework to do a kind of asynchronous divide-and-conquer computation similarly to JDK 7's Fork-Join framework? If so, how could I express an FJ problem with the framework - for example, the tutorial mergesort concept? Code snipplets are welcome.

(I came to the idea based on a resource video I've got in my other FJ related question.)
