UINavigationController leak / understanding popViewController

I have a navigation controller and a table view. When someone clicks on a table view, I do the following:

MyViewController *myViewController = [[MyViewController alloc] initWithImage:image];
[image release];
[self.navigationController pushViewController:myViewController animated:YES];
[myViewController release];

myViewController will save the image.

Now if I go back and forth in the NavigationController I get a leak because a new MyViewController is created every time and apparently popViewController does not release myViewController.

My question is: Why does popViewController not release the controller? How can I deal with this? Put myViewController as a member of my class and check if it already exists instead of creating it every time?

Thanks in advance for your help,

Apparently the problem was that this code was being called on a different thread and then that thread must have another autoresource pool to allow autorelease to work properly.

I usually declare the viewController once in the class, highlight in init and click when needed. Then, in the controller with the viewpoint pressed, adjust the view toviewWillAppear:
