The two differences between a coroutine call and PAUSE are that
1) PAUSE switches to any ready task, a coroutine call to a specific
one (so I am not sure if CO is a good name; what if you want to have
more than two coroutines?).
2) In a coroutine call you may want to pass one or more data or FP
stack items to the other task.
