The "many eyes" canard isn't just about formal reviews, though. It's also about the idea that when something's open source the reviews aren't limited to maintainers or close colleagues who would be involved regardless of open vs. proprietary. What actually seems to happen in the great majority of cases is that the circle of people who actually understand any particular commit is only very slightly greater than it would be otherwise. The bugs are only a very tiny bit shallower, if at all. The fact that it was just one reviewer in this case, despite the code being widely available, only underscores that point.
