No, this isn't how grabs work in X11.  If a window A, implements
XGrabKeyboard() then all keyboard input is assigned to that window --
this is also irrespective of mouse focus away from that window.  No
queueing is done outside of that to other windows if the mouse focus
shifts.  Keyboard events get sent to that window -- but again, this
isn't happening in my case.  (I do a lot of xlib stuff in my spare
time, FWIW.  :P)

I humoured you, with nothing open but two XTerms, and it just happened again.
