48 * This class represents a fiber, which is a light weight sort of thread which
49 * is cooperatively scheduled and runs sequentially with other fibers, swapping
50 * in and out of a single actual thread of execution.
51 *
52 * To define your own threads, create a subclass of Fiber and override its
53 * main() function to do what you want your fiber to do. You can start it by
54 * calling its run() method which will stop your execution and start the other
