title: Node, child processes
body: <p>thus i have been reading every thing in the Node Docs and googled a lot... its still not clear to me how to use child processs...in the best way...
  (My code is running on windows)</p>
  
  <p>Do i need to use exec or fork?</p>
  
  <p>I like to be able to spilt up my code... so instead of running a single loop with 300 (i = 1 to 300) iterations... i would like to run 3 child processes - which executes / loop through 100 iteration each...</p>
  
  <p>So i need to send some variable(s) to each child process...like a start index to use in the loop (i = 0, 100 or 200)...</p>
  
  <p>How do i do this? Can some body show me a complete example?</p>
