streaming partials

Hi everyone! I'm looking for a railsy way to stream partial views in Rails 3.2+. Right now streaming is supported only for yielding via provide. But say I have 10 posts in a blog page, and each post is generated in partial in about 300ms and I want user to start reading the first post immediately as it's ready.

Is it possible in rails now? Is there a way to explicitly "flush" the generated output like in php?
