Correct me if I am wrong, but the caveat here is that the R must be default
values for the bucket. The internal get performed by the coordinating node
handing the INM request does not actually use the R and W value of the INM
It would seem advisable to change this behavior. Maybe the R value of the
internal get should match the W value of the INM request.
