I think the notify call should be like notify((event.object, event))

Ok, the removeIntId function is called and it dispatch the event through
the notify call.

Then, my original subscriber, e.g.:

<subscriber for=".interfaces.IMyInterface
                 zope.app.intid.interfaces.IIntIdRemovedEvent"
            handler=".events.myInterfaceIntIdRemovedSubscriber"
/>

is still not called. I have checked that in the removeIntId subscriber
the object in event.object provides IMyInterface, but this makes no
difference.

Anyway, thanks for this answer (and all the other answer you gave me
before) :-)
