[Ironruby-core] MRI 1.8.7 compatibility

How much effort is it to get 1.8.7 compatible? How much to get 1.9
compatible?

What is driving the push to release 1.0?

My fear is that releasing 1.0 so close to release of Rails 3 without the
ability to run it will do little for IronRuby's image in the wider Ruby
community (who, from my admittedly limited experience, care about weather it
can run Rails or not).
