title: Native threads in Ruby 1.9.1, whats in it for me?
body: <p>So, Ruby 1.9.1 is now <a href="http://www.ruby-lang.org/en/downloads/" rel="nofollow noreferrer">declared stable</a>. Rails is supposed to work with it and slowly gems are being ported to it.</p>
  
  <p>It has native threads and a global interpreter lock (GIL). </p>
  
  <p>Since a GIL is in place, do native threads offer any kind of benefit over green threads in 1.9.1? </p>
