In X11 setups back in the day, it wasn't uncommon for the .xinitrc or whatever startup file you use to end with something like exec xterm, so if that particular instance of xterm exited, then the whole window system went away with it. But that's not typical of modern systems. And even then the computer wouldn't shut down. You'd just be dropped back at your original shell on the console, or if you'd also exec'ed xinit, at a login prompt.
Exactly.  My point was rhetorical -- obviously control resumes 'somewhere' in the stack of all these GUI functions.  But it isn't easy to figure out where.  I even tried this:

  # start xfce4-session normally
touch /aMisc/"$(date +%F--%T)-starting xfce"
#    exec xfce4-session
    xfce4-session
touch /aMisc/"$(date +%F--%T)-stopping xfce"

... just to see if I could get some sense of flow control, but it doesn't work.  I never get to 'stopping'.  It feels wrong.
