Depends. Are you of the "we haven't seen it before, so it can't happen" school of programming, or the "it could plausibly happen, so we should guard against it" school? Consider you get down to that 6K mark - and now you hit that 1K allocation that you didn't bother cleaning up because "we've never seen it before". And then you hit a hardIRQ that *also* didn't bother cleaning up their 1K allocation that *that* kernel hacker "had never seen it before". What happens to your system? And how long is it going to take for you to figure out why every several weeks, your system dies with a totally different random memory overlay?
