title: Is there any cross-platform threading library in C++?
body: <p>I'm looking for some easy to use cross-platform threading library written in C++.</p>
  
  <p>What's your opinion on <code>boost::thread</code> or <code>Pthreads</code>? 
  Does Pthreads run only on POSIX compliant systems?</p>
  
  <p>What about the threading support in the <code>Qt</code> library?</p>
