Try traversing a small tree and print memory usage after each of several executions. If the memory is increasing each time there is a memory leak in the extension. I doubt that is the problem but it's a good test because it will show you with certainty that data is in fact being released when the script exits. Then I would scale down your test. Create a db connection and close it printing memory usage along the way to make sure all memory is restored within the script execution. If that doesn't work there are memory references hanging around *somewhere*.
