title: Render in context memory allocation
body: <p>I posted <a href="https://stackoverflow.com/questions/14418063/core-data-memory-allocation">this</a> question earlier about memory allocation issue and was able to fix it with some help. I'm have another issue which can be seen in the screenshot below. I've tried a few different examples that I've seen online that help release the image context but nothing seems to work. Any help would be great. </p>
  
  <p>BTW I missed [localPool drain] in the screenshot. It's the next line. </p>
