I had a similar bug in my code many many many years ago.
The context was a TCP connection feeding a Versatec plotter. (Remember
them?) Somebody was making a banner for his daughters volleyball team. He
turned the text sideways and set the font size to 3 feet tall. It took the
printer a long time to process a few characters of text. Some timer didn't
handle that case. The fix was only one line.

Does anybody have a checklist of things like that to test?
