True though actually yielding might not be that rare. On the other

Does a closure keep the coroutine in which it was created from being  
collected? If not, then isn't there a problem if upvalues don't get  
closed when the coroutine gets collected? Or maybe we miscommunicated  
since I failed to say "closed" in my earlier message.
