Thanks, when I applied your patch, I still ended up with tasks stuck
waiting with a SIGKILL pending. So I looked into that and came up with
the patch below. With both your patch and mine, my testcase exits
cleanly.

Eric (or Christian, or anyone), can you comment on the patch below? I
have no idea what this will break. Maybe instead a better approach is
some additional special case in __send_signal_locked()?
