My gut feeling is that rushing to make a release date is the wrong thing.

If we have confidence that we can ship something on Monday that is
materially more trustworthy than the current releases, then let's aim to
do that; but let's ship only patches we are confident in. We can do
another set of releases later that incorporate additional fixes. (As some
wise man once said, there's always another bug.)

If what you're saying is that you don't trust the already-committed patch
very much, then maybe we'd better hold off another couple weeks for more
review and testing.
