Hi Tom. Yes I'll make sure I use this API function. I've not actually posted any of my code, so if there are any bugs in the snippets, then they are also bugs in the javascript shell js.cpp.

Yes that's the one. Like it or not, this is the *only* up-to-date piece of code that spidermonkey embedders can look to for examples that I'm aware of. It would be great if the spidermonkey team could do regular code reviews on it to ensure it reflects the current best practices and idioms.
