In a way, weightless threads recall the cooperative multitasking of older Windows and MacOS versions (but within a single application). In another sense, however, weightless threads are merely another way of expressing flow in a program; everything that weightless threads do could, at least in principle, be accomplished with the "really big if/elif block" technique (the last resort of the brute-force programmer).
Essentially a trampoline that passes control from generator to generator.
The technique should be well-known to anyone who has seen how you implement multi-threading using continuations.
Still, a nice demonstration of the power of Python, and a way to familiarize youself (or a friend) with continuations.
