Rails on Rubinius

Haven't tried Rubinius yet myself, but being able to run rails on it is a huge milestone.<p>Some of the benefits of Rubinius, from what I've heard so far:<p>- uses modern techniques to decrease memory usage and increase throughput<p>- less memory change per additional mongrel instance<p>- capability for precompiled code (similar to java .jar files)<p>- better performance<p>- better error reporting<p>- profiling has less impact on performance<p>I think it could totally change the rails landscape as we know it.<p><a href="http://rubyconf2007.confreaks.com/d2t1p3_rubinius.html" rel="nofollow">http://rubyconf2007.confreaks.com/d2t1p3_rubinius.html</a><p><a href="http://www.slideshare.net/evanphx/rubinius-improving-the-rails-ecosystem/" rel="nofollow">http://www.slideshare.net/evanphx/rubinius-improving-the-rai...</a>

This is exciting. The #1 thing holding back Ruby right now is its aging and leaky implementation. I'd say half my debugging time spent on ruby ends with, "Oh, the implementation of ruby has a bug."<p>This is not to say the Ruby guys aren't smart and don't work hard, but you can't squeeze blood from a stone.

The blog post doesn't make it clear: Is ActiveRecord running under Rubinious?

Could someone explain what this is to a Rails guy?
