67 * SA_INTERRUPT is a no-op, but left due to historical reasons. Use the
68 * SA_RESTART flag to get restarting signals (which were the default long ago)
69 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
70 * SA_RESETHAND clears the handler when the signal is delivered.
71 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
72 * SA_NODEFER prevents the current signal from being masked in the handler.
