You might take a look at what Ares does in this regard? It allows one to 
intercept object collection, and lets you know whether the cleanup is of 
deterministic or "unspecified" nature. Invoking a dtor is only 
considered reliable in the deterministic case, so Ares allows one to 
trap and then optionally avoid dtor calls for that other case. One might 
use this mechanism to detect resource-leaks also.
