You're right.

Actually, this is a totally unrelated problem. The problem is that
XGrabKeyboard generates focus events (XGrabKeyboard is called by the
X server after establishing the passive grab with XGrabKey).

So, all keyboard shortcuts cause the window under the mouse to
briefly get focus. I've used Metacity (the GNOME WM) with focus-
follows-mouse, and it doesn't have this behavior when I Alt-Tab.
