I wouldn't call sigset() "reliable signals". (Neither does my SVR3.2 manual!
It contains a warning that sigset() "reliable" signals aren't really
reliable and sigaction() is preferred.)
Anyone here remember BSD 4.1c? If I recall correctly, *that* was the origin
of sigset() --- and it wasn't enough, so BSD4.2 introduced a completely
different signal mechanism which *was* reliable.
