We need a guarantee that gzip will always produce the same output, which
we already know isn't the case and which doesn't look sustainable going
forward.  That's looking rather uncomfortable.  The preliminary results
there point to that being somewhat problematic.

I think we have to do something saner with changelog files eventually
regardless, but I'm curious: how did Ubuntu deal with the binNMU problem
that Guillem identified?  If you binNMU a library on amd64 but not on
i386, as near as I can tell that's going to make the library not work for
multiarch until the next sourceful upload, no?  I think Ubuntu has
binNMUs; haven't you run into this issue?
