Hmm, I wonder if there's a problem somewhere preventing JIT now. Run
JRuby with -d -X+C to debug logging and force compilation. I will look
into it today myself.

I did see fib_ruby compile and was able to get assembly dumps out, but
it performed terribly. I'll try to make extra sure everything's
jitting.

Ahh the joys of a mixed-mode runtime, eh?
