The problems that are solved by PTYs finally "clicked" for me when I read their example of the problematic fseek/flushing. I hadn't seen such a cogent expiation until now.

True, but be warned, that fseek is not a real example. You cannot fseek/lseek on character devices. You would have to use a different technique.
