and yes, if this is the problem, the correct solution is to create an 
separate object type that's designed to manages the resource and act as 
a proxy against it, and then let all operations against the resource 
(from other objects) go via the proxy.

never let more than one object "own" an external resource.

if you need to explicitly kill the external resource, design the proxy 
so you can tell it to ignore (or reject) any subsequent calls to the 
resource from other parts of the program.
