Is it really that bad to warrant this kind of warning? Not knowing about the issue at all, I read from the original description that the wastage is four pages of memory times number of CPU cores, which shouldn't matter much except for small embedded systems.
Or does this something much scarier, like considerably slowing down fast paths?
