I was wrong. I appear to have confused the thread and the non-thread cases.
Perhaps I meant "args->exit_signal = 0". That looks like do_notify_parent won't send it, and thread_group_leader continues to do the right thing.
Baring any additional confusion on my part that cleanly solves the problem of how not to send a signal from a child process cleanly.
My apologies for sending you on a wild goose chase.
