title: Reading data in parallel with multiprocess
body: <p>Can this be done? </p>
  
  <p>What i have in mind is the following:</p>
  
  <p>i ll have a dict, and each child process will add a new key:value combination to the dict. </p>
  
  <p>Can this be done with multiprocessing? Are there any limitations? </p>
  
  <p>Thanks!</p>
