On: Google Bot now crawls arbitrary Javascript sites

I wonder how long it is until someone exploits the parallel nature of the googlebot's (presumably Chrome-based) javascript execution for general-purpose computation like mining bitcoins or something.

I imagine that Google imposes pretty strict limits on computation time for any javascript that is run, so I'm not sure how realistic that idea is.

Yes. If it really were able to deal with arbitrary Javascript sites this would imply that Google had solved the halting problem.

I imagine that those limits are per-page, or perhaps per-domain.
