Antoine Pitrou added the comment:
Amaury is right. In your case you could keep track of the Vectors in the Device
object and invalidate them when the Device is destroyed (using e.g. a WeakSet).
Or Vector could delegate its destruction to Device, e.g.:
class Device(object):
destroyed = False
def __del__(self):
self.destroyed = True
def _dealloc_vector(self, v):
if not self.destroyed:
...
class Vector(object):
def __init__(self, device):
self.device = device
def __del__(self):
self.device._dealloc_vector(self)
