Is this possible?
In case of "kill -9" it is impossible, this signal cannot be caught by a running process. Other cases (e.g. unexpected exceptions or the like) can be handled, but do *not* use __del__ for this purpose! Implement a deterministic resource management, e.g. using a context manager, or by providing an explicit ".close()" or ".cleanup()" (or whatever you want to call it) method, and call this method at the appropriate places.
