Test Case

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_8; en-us)
AppleWebKit/531.9 (KHTML, like Gecko) Version/4.0.3 Safari/531.9

Launching a modal view controller that contains the image picker for the camera
source causes the memory to not be reclaimed even after the modal view
controller is dismissed. I have attached a simple project to demonstrate.
You'll need to deploy it to a device and watch the memory in instruments.

Note: I'm using an iphone 3g with a release build for hte sample app (attached)

Reproducible: Always

Steps to Reproduce:
1.Deploy the sample project attached to a device
2.Launch instruments to watch real memory on device
3.Press button in sample project to launch image picker with camera source
4. Take a picture and touch use camera
5. note camera is not gone but memory is still at same level
Actual Results:  
Memory leak

Expected Results:  
Memory should return to ~ value prior to using camera (as I'm not saving the
image anywhere in this example)
