In QML you can provide a QNAM factory. This is supposed to return a new
QNAM for the calling thread. So having multiple QNAM in an app is not
really an issue?

Such operation should be possible, yet it fails cause setProperty calls:
QDynamicPropertyChangeEvent ev(name);
QCoreApplication::sendEvent(this, ev);
sendEvent cannot be called from another thread the object does not belong
to. Is this a bug? Shouldn't that be postEvent instead?
I have the following problem. I want to have only one QNAM in the (heavily

So I create one QNAM in the main thread when the app starts and assign it
