Yeah, that sounds like the solution, but just look at both attempts to cause 
QProcessManager's thread to exit:

https://codereview.qt-project.org/60586
https://codereview.qt-project.org/102526

For QtDBus, I could hook to QCoreApplication's destruction, close the 
connections, activate the pending replies with a Disconnected error, and stop 
the thread. I'd just rather not do it, if it weren't required.
