[Interest] Detecting if the application is already running from another user account

[Etienne Sandré-Chardonnal]

But how can I test if another app is already running with QSystemSemaphore?
I can set a semaphore with a single ressource (initial value = 1) and lock
it, but there is a single method aquire() which blocks forever if the value
is 0. So I can just make the second process freeze forever until the first
one exits.
