* SA_FLAGS values:
*
* SA_ONSTACK indicates that a registered stack_t will be used.
- * SA_INTERRUPT is a no-op, but left due to historical reasons.
* SA_RESTART flag to get restarting signals (which were the default long ago)
* SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
* SA_RESETHAND clears the handler when the signal is delivered.
