  20. I wouldn't call sigset() "reliable signals".  (Neither does my SVR3.2 manual!
  21. It contains a warning that sigset() "reliable" signals aren't really
  22. reliable and sigaction() is preferred.)
  23.  
  24. Anyone here remember BSD 4.1c?  If I recall correctly, *that* was the origin
  25. of sigset() --- and it wasn't enough, so BSD4.2 introduced a completely
  26. different signal mechanism which *was* reliable.
