It's not my job to design this thing for you, but I guess that's what
I have to do to get you to think out of the box a little bit :-/

Maintain a table, which is only recorded into when the debugging
feature is enable (via sysctl or whatever) which remembers this stuff.

That way nobody eats the space or time overhead unless the debugging
feature is enabled.

Wow, I had to use every brain cell I have to come up with that one!
