Actually there are quite a few organisms where stress intentionally causes mutations and this is advantageous so isn't bred out. So as long as you gate high mutation rate behind some trigger it is beneficial. If a population is dying due to too little water, for example, it is time to up the mutation rate and try to come up with something that can survive.
