title: Does Windows 7 recycle process id (PID) numbers?
body: <p>I have this little test program that tracks PID's as they are created and shut down. 
  I am investigating a problem that my program has found and would like to ask you about this
  in order to have a better idea on what's going on.</p>
  
  <p>When a windows process is started, it gets a PID but when the process is shut down, does the PID
  become retired (like a star basketballer's jersey number) or is it possible for a new, entirely 
  unrelated, process to be created under that released PID?</p>
  
  <p>Thanks</p>
