Most operating systems have implemented realtime signals incorrectly

Since they all do such a spectacular job of delivering different (buggy) results, I have to believe support was 'roll-your-own' on each platform. There's no reference implementation of POSIX features? No test cases? I guess there are now.

I helped deliver the 1st POSIX implementation, the year it was specified, on an old real-time OS called CTOS (BTOS if you bought it from Burroughs/Unisys). I wonder if we got it right...

There's test suites: http://www.opengroup.org/testing/downloads.html , though I don't know what they cover - posix is highly componentized.
