Not at the moment. I'm mostly doing some ugly hacks to get stuff working and generating a list of bugs for things we need to fix properly. Looking at my branch I think there's one small change that we will want to do PR for in the end, and some dependencies that we may want to make platform dependent (though they recently did change a couple for JRuby, which also helps us). Pretty much everything else I hope to back out when we've fixed a few of the root causes.
