Yes. I hold the opinion that there is not a whole lot of reason 
why something like byChunk can't be fast like we might desire. If 
it's down to getting chunks of data the right way, whatever that 
is, and the problem is an IO bound problem, then I don't see why 
we can't submit pull requests to offer optimisations on it. I 
don't think we need to go down this "the way it does IO isn't 
fast enough so we need to replace it" route. Just optimise the 
existing thing more.
