Do you think that could be acceptable?

Think so, it's a sysctl poke, 'nobody' ever does that.

Cool, so... I'll keep lazy update for system default.

Ah, I think I misunderstood. I meant to say that since nobody ever pokes
at sysctl's it doesn't matter if its a little more expensive and iterate
everything.

Also; if you always keep everything up-to-date, you can avoid doing that
duplicate accounting.
