Add new arity for release method #6
Description
When you try to dereference a ResourceHandle, it checks to ensure that the handle is still valid before returning. When it is not still valid, it throws a generic exception: "user has no handle on this resource.
A new arity for the resource release method that allows you to pass a function intended to catch and handle that exception (perhaps by suppressing or re-throwing or throwing a completely different exception) when and if this function is specified.
This would allow a possibly very low-level asynchronous task to handle the expiration of a resource handle based on logic known only to higher-level components in the system (e.g., choose to suppress the exception rather than log it because it's a "nominal" exception).
To Be Determined: details of context passed to this function.
