However the threads library prevents letting this be used as it silently bypasses this SIGCHLD processing. Here is the man page snipet: SA_NOCLDWAIT If this bit is set when calling sigaction() for the SIGCHLD signal, the system will not create zombie processes when children of the calling process ex- it. If the calling process subsequently issues a wait(2) (or equivalent), it blocks until all of the calling process's child processes terminate, and then returns a value of -1 with errno set to ECHILD. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
