title: Bittorrent Tracker Update?
body: <p>In a bittorrent client the first response from the tracker will contain a list of peers. When the tracker is contacted for an update after the first response, will any of the peers sent in the second response be the same as in the first response?</p>
  
  <p>The reason I ask is that I don't want to waste time checking whether any of the peers in the new list are the same as the new list.</p>
  
  <p>Thanks in advance</p>
