I don't think you can quote me saying "I object to this code". I posted
a detailed review of the API and implementation on X86 outlining lots
of issues. Some got fixed, but many others are left unresolved at this
point. And I will post some more shortly.

I don't think that because this code is coming from you, it should be
allowed to short-circuit the established release process. You have
to respond to questions, fix issues like everybody else and if that
slows down the integration you cannot blame the reviewers for it.
