[Development] Should QFileSystemWatcher be thread-safe? (Qt 5.8.0)

[Adam Treat]

Simon just gave a talk about signals and slots on different threads and 
the internals of how Qt handles this at CppCon in Seattle yesterday. I 
would suggest you have a look at the video of his presentation when it 
comes out. You could also look at the documentation: 
http://doc.qt.io/qt-5/threads-qobject.html with particular attention to 
"Signals and Slots Across Threads"
