I noticed that running a python script that outputs very very long lines
gave horrible screen updating performance. The same data when written with
short lines was OK.

I've occasionally noticed similar issues with debug output (big
structures) in Slime Repl mode (where such output has a mouse-face
property, I believe).

Me too; me too. I assume that turning off font-lock in the buffer
would help, but naturally I haven't actually _tried_ that :-)
