Numerical renormalization group calculations have shown that any nonzero RKKY coupling between a pair ofspin-~ impurities destroys the zero-temperature critical point responsible for the marginal-Fermi-liquid behavior of the single-impurity, two-channel Kondo model. Here we report recent progress on
