I just grabbed the latest SDK and recompiled dartbox2d with the latest dart2js. Last time, I reported some performance issues, this time I'm seeing some stability issues. It looks like some numeric inaccuracy has crept in.

I haven't pinned down exactly where yet, but demos that were stable before ( now just explode. Under Dartium these still work as expected. 

I don't want to check in the JS versions that are broken, obviously, but I can point people at a version or zip something up if necessary.
