Ah, thanks. I was under the impression that it was neither. (see below)

In my case, it was simply because of the existence of the mallocd member. I 
still don't understand what its role is. In both cases #1 and #2, it doesn't 
matter what value I set it to since the channel won't care. This didn't seem 
to make sense, so that's why I assumed that the channel would use the mallocd 
member and free the frame itself.
