// This is an example of how cooperative multitasking could be
// emulated in Javascript.

// Javascript has only generators, which are "half-coroutines",
// meaning they can only yield to their called and not other
// generators. We can add a special "coordinator" generator and
// a yielding convention to make it look almost exactly like
// we have full coroutines.

// Note that the yield* operator is not what we need here.
