Help How do you create a rope at runtime?

There’s a hint globe in the manual with a direct answer to this :

“Remember that you don't have to rely on StartCoroutine to run a coroutine, or run it asynchronously. You can manually advance it using IEnumerator.MoveNext.“

Oh, for sure, I'm doing that. But I guess that relies on those coroutines not yielding WaitForXXX right? Because there are expectations on rendered frames, time, etc. I just want to make sure.
