To be honest I'm very sceptical about this. I fully accept that IOSd is
multithreaded. But I'm having difficulties accepting that each IOSd process
would be own thread scheduled by Linux and that native/IOS
run-to-completion scheduler isn't used at all.
But we're out of scope for ISSU thread in nanog-ml, I think. I do
appreciate always when vendors pitch in in public forums, so thank you for
that Pete.
