title: Xcode Instruments stops recording when iPad app leaves the splash screen
body: <p>I am writing an iPad app and I would like to use Xcode Instruments to see if my app has any memory leaks.  I have used Instruments successfully before but with Xcode 4.0.2 recently with this app I have the problem described in the title.  It only works very rarely.</p>
  
  <p>Steps to use Instruments:
  - From the Xcode menu: Product>Profile
  - Choose the Leaks instument
  - Watch Instruments start recording allocations and leaks while the app shows its splash screen.
  - The app's initial view controller becomes visible and Instruments stops recording at the same time.</p>
  
  <p>Am I doing something wrong?  Is this a bug in Instruments?</p>
  
  <p>Any help would be appreciated.</p>
  
  <p><b>Edit:</b></p>
  
  <p>Instruments works on the iPad simulator but not the device (iPad 2)</p>
