Thanks Ben, I tried setting it weak, and noticed that it still was considered "not near death". However, after a while, this did change. So this is consistent with your assertion that it's not instantaneous.
I was going to expose this API in my Java bindings, but maybe I'll skip if for now. Do you know what this API would be useful for, or have you seen real world examples of people using it?
