Thanks for the elaborate response, now I much better understand what you're trying to say.
This is different from the examples you mention: there is no external software that creates the sandbox (whereas with Java and Flash you had to install those as plugins). It's really just Javascript as it is built into the browser. Any vulnerability in this "sandbox" is a vulnerability in the browser, not some 3rd party plugin.
Put differently, this pypy emulation is no different from the Javascript API that was in your browser already. This isn't a new plugin, just using Javascript to emulate Python through the Pypy interpreter.
