Yeah, that's what I already do.

Yes, this is *exactly* what I'd like to do.
Yes, it was already said that this wasn't possible with the current code
of BuildBot and that doing this would require a lot of hacking. I'm going
to dive into BuildBot and do this myself, instead I used a workaround so
that whenever a builder fails, it removes all tarballs uploaded for this
revision (the name of the tarball starts with "r<N>-" so it's rather easy)
Nevertheless, I think this is the kind of feature that would be cool to
have if someone feels like implementing this at some point. :)
