So the big remaining ones for me are the /proc/<pid>/stack (stack
pointers) and the /proc/net/* ones.

I'm a bit disappointed that those haven't been fixed already and
aren't even in this series..

Since I was the proponent of the whole "leaking_addresses" script
model, I guess I can't complain when %p isn't then just made to hash
everything, but it does feel like this has been dragging out a bit..
