You have to let Zope know that the object has been modified so
it knows to commit it to disk.

x = self.list
x.append('something')
self.list = x

will do that.  Hmm.  Actually I suppose that

self.list.append('something')
self.list = self.list

would also work.  (The point is for __setattr__ to get called so
Zope can notice that the object has changed).

There's also a property you can set on self to notify zope of the
modification, but I forget it's name.
