[Interest] Signals, slots before the event loop starts?

I've now come across two places in my code where this is an issue (at various states of initializing)
In a QObject who is exported to QML, and is instantiated just below the top-level Window:
// in the object's open() method:
qApp->quit(); // won't actually quit - no use if I can't use the serial port. (because another instance is using it)
Then I have a ready() signal that is emitted when the serial device is ready, however the QML, when I hook onReady, it never gets called. I have to use a Component.onCompleted at the top level. However, there is async serial I/O happening, so there is at least one event loop?
What can I do to make sure these things work?
