In our current system, this function is called 'schedule()';
and it takes an 'args' tuple.  It doesn't transfer control, it just
makes the other coro ready to run ASAP. [i.e., next trip through the
event loop it will be added to the set of 'runnable' coros].

Here is our coro::condition_variable::wake_one() for context:

    def wake_one (self, args=3D()):
        for coro in self._waiting:
            try:
                schedule (coro, args)
            except ScheduleError:
                pass
            else:
                self._waiting.pop(0)
                return 1
        else:
            return 0


[ScheduleError is thrown if the coro has already been scheduled]
