title: Detecting leaks in Cocoa thread?
body: <p>I have been working on an application in Xcode for a while now and had previously detected a lot of memory leaks using Instruments. Fast forward a few months and I have added threading to my application and Instruments will not show any memory leaks even though it has a growing memory footprint.</p>
  
  <p>Does Instruments not detect memory leaks in threads I create? What could be the reason for these leaks flying under the radar?</p>
