My current effort does roughly 400 lines per tick on a 1ghz machine,  
not counting setting the htmlText. (note that it doesn't handle block  
comments, among other things)

More importantly, it seems to scale linearly. Colorizing a script  
four times as long as the libURL script takes four times as long as  
the libURL script.

Given that, it would be nice to be able to handle truly mammoth  
scripts. I think you're right that it would require some sort of  
color-on-the-fly-as-you-scroll method. Given the speeds we've  
reached, live colorization while scrolling doesn't seem out of the  
question.
