; 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.
; SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
; SA_NODEFER prevents the current signal from being masked in the handler.
;
; SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
