title: iPhone/Instruments: what's about the "malloc" entries in object summary?
body: <p>I'm performance tuning my iPhone/iPad app, it seems like not all the memory gets freed which should be. In instruments, after I simulate a memory warning in my simulator, there are lots of "Malloc" entries left; what's about them? Can I get rid of them, what do they mean/what do they stand for?</p>
  
  <p>Thanks a lot,</p>
  
  <p>Stefan</p>
