title: CFString Memory Management Issue
body: <p>I am developing an app for the iPhone and am encountering some memory management issues. During execution of the app the live bytes continuously increase without bound. I have tried to track down the issue within my code but cannot seem to find anything that would cause the live bytes to increase so dramatically. The one thing that I have noticed during execution is that the allocation for CFString(Immutable) increase the most rapidly and never decrease or stay constant. Does anyone have any idea why this may be happening? All that the app is doing during this execution is populating a table view from a local array or strings, then downloading another array of string objects and populating a different table view. I am using ARC.</p>
