Well, this is not true. My main objection still holds. I simply do not
think all the additional code is really worth it. Not enough to nack the
patch, though, of course. I am not questioning that the watchdog might
be useful for debugging. I just think that what we have currently tells
us enough to debug issues. Sure, you will tell that this is not
reliable, but I will argue that this should be fixed because that makes
sense regardless of the stall warning.
