title: worker queue for nodejs?
body: <p>I am in the process of beginning to write a worker queue for node using node's cluster API and mongoose. </p>
  
  <p>I noticed that a lot of libs exist that already do this but using redis and forking. Is there a good reason to fork versus using the cluster API?</p>
  
  <p><strong>edit</strong> and now i also find this: <a href="https://github.com/xk/node-threads-a-gogo">https://github.com/xk/node-threads-a-gogo</a> -- too many options!</p>
  
  <p>I would rather not add redis to the mix since I already use mongo. Also, my requirements are very loose, I would like persistence but could go without it for the first version. </p>
  
  <p>Part two of the question: 
  What are the most stable/used <strong>nodejs</strong> worker queue libs out there today?</p>
