Using globals or TLS would introduce subtle reentrancy problems when calls are nested. I don't want to create more C-APIs we need to support long-term, either. Likely we will introduce something like prelude.rb into the extension build system (and/or use the new iseq loader features). It would speed up load times, too. JRuby doesn't use our current prelude.rb, I hope. Fwiw, I like the Rubinius philosophy of using Ruby as much as possible a lot and tried to contribute there back in the day. I just do not like their non-Free-service-based development, C++, the isolated "Ruby environment" model, or slow startup times.
