     If you destroy and re-create the QCoreApplication object you must call
     load() again.

+    QCoreApplication, QNetworkInformation should always first be loaded
+    in the same thread as the QCoreApplication object. This is because the
+    object will also be destroyed in this thread, and various backend-specific
