It looks like it's more than just font-lock. With font-lock off, if I
hold down C-p to move up in the buffer, drawing new pages takes up to
a full second (subjective). And typing past the end of a line has a
hard time keeping up with my typing. Even typing this message is very
laggy. I will have to do some profiling to see what it going on.
Nothing in my configuration has changed very drastically since
February, when things were working quite nicely.
John
