Deterministic Disposable

Here is a challenge, get this to work:
///<summary> /// Executes the given handler when the instance is disposed /// of using the Dispose(instance); /// Note: Doesn't cause memory leak ///</summary> public void OnDisposable(object instance, Action<object> action); ///<summary> /// Executes the previously registered Action for this /// instance ///</summary> public void Dispose(object instance);
The key part here is to get this to work without causing a memory leak. Furthermore, assume that you need to handle this scenario as well without causing a leak:
object instance = new object(); OnDisposable(instance, delegate(object obj) { Console.WriteLine("Disposing of {0}", obj); });
