[PyQt] with PyQt's input hook, is it expected that sending to stdin dismisses a modal dialog created in response to a signal?

Looking at qtcore_input_hook() in qcoreapplication.sip, it's easy to see why this happens, and it seems like a reasonable compromise between permitting modal dialogs and avoiding blocking the Python prompt. Still, google doesn't reveal a definitive answer, and I'd like to be sure that I understand the situation.

I don't think it was specifically designed to do that - just that's what happens to happen.
