Comment (by bobince):
> I don't think it's correct to clear receivers_called = [] like that
inside the loop
It should be fine as long as the loop is in the same scope as the
definition of receivers_called. But yes, it might be clearer to reset the
list without rebinding it by doing `del receivers_called[:]`.
> Sadly, this does not fail for me at any iteration
That's because the new example stores a reference to `sender` in
`signal_calls`, which prevents the sender being destroyed and its id re-
used.
If you store `id(sender)` or `str(sender)` instead you'll get the error
again.
