Right. Everything needs to be scaled. Everything needs to be in
perspective. Losing 1 kilobit per day is indeed trivial; even losing
one kilobyte per day, which is what I assume you meant :), isn't
significant. But it's not usually per day, it's per leaking action.
Suppose your web browser leaks 1024 usable bytes of RAM every HTTP
request. Do you know how much that'll waste per day? CAN you know?
