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.
