title: Python time.clock() - reset clock value with threads
body: <p>I see time.clock() on Windows 'starts' a timer when called for the first time, and returns elasped time since the first call for calls after that. I read that the only way to restart the clock is to start a new process. </p>
  
  <p>Is starting and killing threads supposed to restart the time.clock() as well? It doesn't seem to be working right now. If not, is the only solution to re-launch the entire executable?</p>
