That Emacs instance has been burning 100% CPU all day. I can interrupt and single step it in llbd from another Emacs. Is there any way to unwedge Emacs? E.g., would forcing read_char to return Qnil, Qt or something cause corruption? Would invoking, say, Fbury_buffer_internal (Fcurrent_buffer ()) regain control or blow it up? I'll leave it overnight in case it reads the ^G^G^Xk^M I typed. Peace --Devon P.S. Obviously, long stretches of non-newlines wedge Emacs for ages, because redisplay assumes there are no long lines. Perhaps the docs mention some workaround I missed? Redisplay has been buggy for over a year now, glitchy blank windows, etc., but that's not today's bug.
