Interesting.
I don't think it is SIGCHLD, because you can "strace" the waiter in one
window, and send it a SIGCHLD _by_hand_ in the other window, and it will
do a new "wait4()", but still not pick up its zombie children.
So it looks like wait() itself is broken, and doesn't pick up the children
for some reason. It just returns 0.
Ingo, Roland - Badari included a test-program in his post on lkml, and I
can trigger the behaviour on ppc64, even if I can't see what's wrong yet.
Mind taking a look?
