More interesting in this context seems to be the subtle change in SA_NOCLDSTOP behaviour with XSI enabled noted in the spec https://pubs.opengroup.org/onlinepubs/9699919799/functions/sigaction.html SA_NOCLDSTOP[CX] Do not generate SIGCHLD when children stop [XSI] or stopped children continue. Should this detail be documented, too, for this flag? Get SIGCHLD only if continuing, not when stopping unless with XSI? Alrighty then, Thomas -- sent from mobile device, trustworthy or not
