[Disclosure: I work at Google but don't work on anything related to the crawler] All this anger aside, I'm actually pretty impressed with the world we live in and proud of my company. Think about how far we've come that merely crawling and indexing the vastness of the internet is so mundane now. Now we should expect the whole internet to be downloaded and executed. That's got to be a great security and integrity problem. Surely someone had tried to break out of the sandbox. Can that be abused to affect SEO of other sites. The easy answer is "spin up a new VM for each page" but that would slow the indexing process down by orders of magnitude.
