title: "po" command in Xcode 4.6 is very slow the first time
body: <p>I upgraded to Xcode 4.6 and whenever I debug and I execute "po" for the first time to inspect an object, the debugger takes like 1 minute to return. After that, every "po" command will work fast as usual. </p>
  
  <p>Are you guys seeing this as well? Any fix?</p>
  
  <p>Thank you</p>
