We are currently creating a signal socket and socket notifier before the
Qt event loop itself has been created. Thus, when we receive a signal,
we are not actually notified when we write that signal number to the
signal socket.
This was also the source of the following error message being displayed
on every launch of the browser:
QSocketNotifier: Can only be used with threads started with QThread
