From what I have read on XSetInputFocus and XGrabKeyboard in the Xlib manual, I
do not see why XGrabKeyboard is needed either.  I say this because according
to the Xlib manual, if a valid focus window is passed to XSetInputFocus, it
does exactly what XGrabKeyboard does with its owner_events flag set to True in
terms of keyboard events.  Which is exactly what is done in the XGrabKeyboard
check above.  So to me the XGrabKeyboard looks like a reduandant call.  However,
since I am not well versed in Xlib programming, I cannot tell why it was done
this way in the first place.  There must be some reason for it as I do not
think it is there by mistake, but then again ....
