title: CoreGraphics Library Leaking in iOS4 and not iOS3?
body: <p>I am using instruments to check for memory leaks in my app.. iOS 3.1.x doesnt show any leaks.
  However, when I do the same test on iOS4 iPhone I am getting leaks from CoreGraphics library.</p>
  
  <p>Did anyone had similar problem? is it problem in the OS itself?</p>
  
  <p>Many thanks</p>
