What does "unhappy" look like?

Does xemacs terminate by itself?  Or is always manual by you?

Is it necessary to kill both xemacs and R?  I would have thought that
killing just R would be sufficient.  The value of killing just R, and
keeping the xemacs is that the *R* buffer would still be there.

What is the value of the emacs variable:
  font-lock-maximum-size
