title: How does one tell if an IDisposable object reference is disposed?
body: <p>Is there a method, or some other light-weight way, to check if a reference is to a disposed object?</p>
  
  <p>P.S. - This is just a curiousity (sleep well, not in production code).  Yes, I know I can catch the <code>ObjectDisposedException</code> upon trying to access a member of the object.</p>
