Redisplay time is [at least] O(n) when n is the length of
the longest line in the current window. So just use a sufficiently
long line to make redisplay take more than 1 second.
In the case you raised, redisplay takes 4 seconds on my 1.4 GHz laptop.

Huh? No.
YOU said YOU have this problem and wanted us to work on a fix.
Now you say it is not an issue anymore. So I'm confused!
