Workflow: How can I signal one branch of a parallel activity to end from another branch?

I have a workflow with a parallel activity, where one branch does work and the other has a receive activity that can shut the workflow down (is the proper way to do this with a HandleExternalEvent instead?). The problem, of course, is that if the receive activity is never called, the work branch completes and waits on the receive activity branch. How can I signal the other branch to close the activity? I've toyed a bit with using a listen activity to hold the receive activity and a custom event activity, but I'm missing something on how to make that work, as well.
