title: A recommendation for a good programming book in Threads and Concurrency in c\c++
body: <p>HI all!</p>
  
  <p>I'm currently taking the course Operating Systems in my university. We mainly study theory and have simple exercises in c++ to exercise some theoretical principles. 
  I want to study more about the practical programming in concurrency and threads in c\c++ and i was wondering if any of you have a good book to recommend on.</p>
  
  <p>Thank you all    </p>
