+ *  Created by Jens Alfke on 4/29/08.
+ *  Adapted from Steve Dekorte's libCoroutine:
+ *  <http://www.dekorte.com/projects/opensource/libCoroutine/>
+ *  by putting it on a piece of wood and banging a few nails through it.
+ *  No, actually I removed all the stuff for cross-platform support, leaving only the simple
+ *  code that works on Mac OS X 10.5, and then cleaned things up a bit.
