> The evolving "Unix attitudes" became non Unix. Bloat is everywhere in Linux.
I'm not sure what you mean. The point of the article is to explain that older implementations played fast and loose with signal handlers that might do all sorts of operations that turned out to be unsafe. As Chris points out, the current POSIX standard is very constrained! You call some specific functions, you set a flag, you GTFO.
So I don't know what you are on about regarding bloat, because if anything in Unix has slimmed down since V7, it's signal handlers (see also the discussion about Bourne shell exploiting SIGSEGV to allocate memory.)
