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?
