title: Why does Tornado take so long to die when I hit ctrl-c?
body: <p>When developing a Tornado application, I frequently want to restart the server to pick up new changes. I hit ctrl-c to stop the server, but with Tornado, this seems to be very slow. It waits for many seconds before shutting down, or doesn't shut down at all when issued a ctrl-c.</p>
  
  <p>What's weird, is if, after clicking ctrl-c, I make a new request to the server (by, for example, refreshing my browser that is pointing at the server), it shuts down right away.</p>
  
  <p>Anyone know how to explain this or fix it? Anyone experienced something similar?</p>
  
  <p>(Note, this is on Windows.)</p>
