In the discussion of CLONE_VM I find this sentence: > If the CLONE_VM flag is specified and the CLONE_VM flag is > not specified, then any alternate signal stack that was > established by sigaltstack(2) is cleared in the child > process. Which simply doesn't make sense. I guess one of them should have been the name of another flag.
