The problem with continuing to delay 3.0 while we have known bugs
is that bugs generally come in at an even rate, so we *always*
have known bugs, and so "we found another bug, let's delay 3.0
again to put in a fix for it" is a recipe for never doing a release.
That's why we gradually wind up the bar for "should this go in",
from "any bug" to "regressions" to "really really serious showstopper

We never do a final release without a last rc (it is too risky),
so that is not an option.
