Review comment:
I don't understand it how is it working right now. Where are the
remaining (non last) buffers recycled? And why do you have to handle the last
buffer differently? As I mentioned before, I think:
> The ownership of the buffers returned from the iterator should belong to
the caller of next() method.
so buffers' ownership should be handed over, and owner should be always
responsible to recycle it when it's done using it.
