I was under the impression that graphite did this, and it's fast turning
into the new default tool for this sort of thing. However on closer
examination it also seems to be limited to 1 second intervals. That's what
you get for assuming...

So since I can't really suggest anything better, and given Florian's
interesting use case of max temperature logging in combination with that
consolidation idea... I'm changing my mind about this.

Your consolidation patch looks great, and works for me. Florian, I'd
recommend merging it.

Thanks, Kieran!
