Hello,
in a class derived from Persistent, which attributes are stored?
All or only
those thar are declared in the interface?
All.
def __init__(self):

self.queue seem is empty each time I restart Zope.
Mutable objects, such as sets, lists, and dicts, can't inform their
persistent parents when they change, so changes to them are not
persisted. Use a persistent mapping in the persistent package (or a
btree); or set obj._p_changed=True when the dict changes; or use an
immutable data structure that must be replaced on the object instead.
