Is that really true? That is, I assume that you mean the latency with 
this proposal is due to the recursive still having to go fetch all the 
pieces. However, if the recursive already has some or all of the answers 
in its cache, this proposal reduces the latency compared to the stub 
asking for each piece. Or, I might be misunderstanding why you think 
there is no latency reduction.
