Imagine a:

public class Global : IDisposable 
{
    private static readonly List<IDisposable> Disposables = new List<IDisposable>();

    public void ApplicationStart()
    {
        var heavyLifter = new HeavyLifter();
        Disposables.Add(heavyLifter);
    }

    public void Dispose()
    {
        Disposables.ForEach(d => d.Dispose());
    }
}

I am somewhat inexperienced with IDisposable. Is this a viable pattern?
