Thanks indeed; I did not spot this issue either.

Would it be possible to circumvent this issue by moving the thread 
object onto its own thread too?

    Foo() : QObject(nullptr) {
       moveToThread(&m_thread);
       m_thread->moveToThread(m_thread);
       m_thread.start();
    }


Looks like the much debated move-QThread-onto-its-own-thread 
antipattern, but it's not the same obviously.
