Fibers are non-preemptive threads. They can be used for co-routines or event-driven applications. The fibers do have some limitations: their frame stack is limited to 256 total, and their hardware stack is limited to a size of $C0. So no deep recursion with fibers. Also look at Long Jump for a slightly different take on a similar theme.
