No I looked into that code a bit further at the time, it talks about
checking a variety of scoped signals including "global" ones. So I at
least simply don't know the flow for that signal and don't understand
the issue on that side. But its okay for us we circumvented it by
changing the basis on which we issue the kill().

Sorry it doesn't make any sense for me to make it switchable in /sys or
anywhere else, there's only one right thing to do at each scenario. I
guess take a look at it when the patch comes and see what you can find
that is wrong and we can go on.
