I disagree. There's no way we can release anything this
century if we keep on checking in things are branch is 
frozen. The time window for commits is over at this point.
If this patch breaks one of release compilers, we'll spend
another week just to get back to zero regressions.

The final decision is up to Thomas, of course, but I hope
that no code changes will be allowed, no matter what.
