Yes, obviously.

I am actually not so sure about that. With threads, you code knowing fully that your code can be pre-empted anywhere. It's uniform and simple. With co-routines, you have to think about the additional logic of when to yield, and that's very distracting. As a matter of fact, I tend to create more deadlocking code in a co-routine environment than in a threaded one, because - among other things - I'm permanently tempted to get clever.
