Fontification of long code blocks can be very slow. The patch, which should be in another other email, mitigates this by adding an option to delay the fontification after the user has become idle by using idle timers. This seems to be faster from my limited testing, but I'm not sure if something will go horribly wrong because of the timers.
There is a trade-off in that there will be no syntax highlightinting when the user is typing. I don't know how to keep existing fontification so it would be great if somebody could share a solution to that. I have signed the copyright papers so that shouldn't be a problem. This is my first patch submission so any suggestions for improvement are welcome.
