  63 * SA_RESTART flag to get restarting signals (which were the default long ago)
  64 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
  65 * SA_RESETHAND clears the handler when the signal is delivered.
  66 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
  67 * SA_NODEFER prevents the current signal from being masked in the handler.

  70 * Unix names RESETHAND and NODEFER respectively.
