No, you can depend on it to collect memory, but you need to run your own pools if you need to create and get rid of large amounts of temporary objects. And you're going to need to use Instruments' object alloc instrument to figure out where your code is creating large amounts of temporary objects. Do not use Activity Monitor as a profiling tool.
