[Pharo-project] Dynamic content in inspector??

Hello all, With the understanding that I am doing non-trivial FFI work and could have completely fried my image already, I'm wondering if this is a common Squeak/Pharo newbie kind of amazement: I create and inspect a new instance of something that has a #printOn: method, and the contents of the inspector's workspace change with time. I have seen inspectors update to track objects in the past, but this behavior is unwanted. I thought of finalization, but that appears not to be happening (nor should it be with the object inspected). I will keep looking, but plausible explanations will be appreciated. Bill
