So thinking about this, do you think these bugs are all unique or are there a small set of new bug categories that were found and once automated resulted in many separate bug fixes?

For many of the new bugs, do we think they would all have been prioritized in the past? Are these all critical bugs that would have all been addressed in a timely fashion or are they getting done because its easier to do.

Another way to ask it would be, do we think we're discovering that Chrome had more big holes than we thought or are we raising the security bar by fixing smaller holes?
