What about a change that's already been committed but another committer
feels caused a regression?  If that gets a -1, does it get reverted
until things are sorted out, or...?

In the situation that started this discussion, a change had already been
made and it was only later realized that it caused a regression.  Piling
on to that, the regression was entwined with other important changes
that we wanted to include in the release.

Having a system where when the commit was made is a driving factor seems
like it would potentially reward people who pushed a change early by
giving them the upper hand in such a discussion as this.

Ultimately though, I still agree with Andres that this is something we
should act to avoid these situation and we shouldn't try to make a
policy to fit what's been a very rare occurance.  If nothing else, I
feel like we'd probably re-litigate the policy every time since it would
likely have been a long time since the last discussion of it and the
specific circumstances will always be at least somewhat different.

Thanks,

Stephen
