There are plenty of possibilities, depending on the model we use.

For example, one could disallow writing more than one line in a
statusbar, since the statusbar has only one line, and allowing more
lines would need other specifications, such as a "delay time", but if
one wants to write two delayed consecutive lines he needs the
possibility to atomically do so.

Many other examples, that I can think of now, are connected to some form
of animation, but I guess that there are other possibilities.
