title: multiprocess or threading in python?
body: <p>I have a python application that grabs a collection of data and for each piece of data in that collection it performs a task. The task takes some time to complete as there is a delay involved. Because of this delay, I don't want each piece of data to perform the task subsequently, I want them to all happen in parallel. Should I be using multiprocess? or threading for this operation?</p>
  
  <p>I attempted to use threading but had some trouble, often some of the tasks would never actually fire.</p>
