ThreadKill not handled by ThreadFiber #2773
Description
Celluloid tests are failing consistently on JRuby (jruby-1.7.19 and jruby-head from RVM) with stacks like the following:
Exception in thread "Ruby-0-Fiber-3" org.jruby.exceptions.ThreadKill
at org.jruby.RubyThread.throwThreadKill(RubyThread.java:517)

On jruby-head it's:
Exception in thread "Ruby-0-Fiber-1" org.jruby.exceptions.ThreadKill

Isn't ThreadFiber.run supposed to catch and handle ThreadKill?
Let me know if I can debug further (though coming up with a specific short snippet may be hard).
