title: Xcode 4.3.2, issue with running on simulator
body: <p>I have been having this weird problem with Xcode 4.3.2, of course after the recent update.</p>
  
  <p>After successfully building and running on the simulator several times, xcode seems to not be able to connect to the simulator and can't even stop the project; it's like the simulator does not exist. I have tried:</p>
  
  <ol>
  <li>Stopping the project – doesn't work.</li>
  <li>Quitting the simulator – doesn't work, xcode still shows it's running on the simulator even when I quit the simulator.</li>
  <li>Cleaning the project – doesn't work.</li>
  </ol>
  
  <p>I have to force quit xcode to get it communicate with the simulator. Nothing else works. It gets quite frustrating to do it every half an hour. This only started with 4.3.2.</p>
  
  <p>I always stop before building and running, so it is not an issue of simulator/xcode getting thrashed by me.</p>
  
  <p>Any suggestions?</p>
