>Description:
THe man page (and also the kernel) do honor SA_NOCLDWAIT for sigaction.
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.
