183 reasons of efficiency, when listing killed groups, this specification
184 is ignored altogether. If the spec is changed considerably, your
185 output may end up looking strange when listing both alive and killed
188 If you use %o or %O, reading the active file will be slower and quite
189 a bit of extra memory will be used. %D will also worsen performance.
