Please see the minimal test code below. In short connecting a signal to a
functools.partial slot breaks the expected moveToThread behaviour.
Reasonable, I'd say, once you think about it. I'm just asking some suggestion
about how this issue can be addressed. I thought about reimplementing some
signal class with a connect_partial method that stores bound args.
Python 2.7.3, Qt 4.8.2, PyQt 4.10 on Linux.

app.mysignal.connect(a.standard_slot, QtCore.Qt.QueuedConnection)
app.mysignal.connect(functools.partial(a.partial_slot, "aParam"),
QtCore.Qt.QueuedConnection)
timer = QtCore.QTimer()
timer.setInterval(1000)
timer.timeout.connect(app.mysignal.emit)
timer.start()
app.exec_()
