Coro patch

[Charles Oliver Nutter]

Ok, bug report time! :)

It looks like it's crashing again once Hotspot JITs.

This works:

jruby --1.9 -Xfiber.coroutines=true bench/bench_fiber_ring.rb 10 100 100

But this doesn't:

jruby --1.9 -Xfiber.coroutines=true bench/bench_fiber_ring.rb 10 1000 100

Here's the console output, and I've attached the log.
