I surely hope most people running raid5 are not seeing that level of unexpected shutdown, let along in a degraded array, If they are, the atomicity issue pretty strongly says they should not be using raid5 in that environment. At least not for any filesystem I know. Having writes to LBA n corrupt LBA n+128 as an example is pretty hard to design around from a fs perspective.
