Hello all.
Previously discussed here: http://www.ruby-forum.com/topic/4402823

I would expect the following code to eventually run the finalizers mentioned:

def finalized_puts bad
    ObjectSpace.define_finalizer(bad) { print 'collector run', bad }
end

loop { finalized_puts [] }

This works in jruby as expected, but not in MRI.  This has the unfortunate side effect of making define_finalizer *very* difficult to actually use right http://www.mikeperham.com/2010/02/24/the-trouble-with-ruby-finalizers/

Cheers!
