It requires compiler support, though.

- Place retain/release at each place expected by Cocoa programming 
conventions, as if manually written

- Do a second pass with data-flow analysis to remove retain/release 
pairs that don't escape current scope.

If you have an Apple account search for:

conventions and allocators
