There is at least one situation in unix where it is (almost) absolutely
necessary: When you need to restore a terminal's state.

If I initialize ncurses natively in some object, I need to either
have the user manually restore the terminal, or do it during
finalization. I prefer the latter because it is easy to write buggy
code that never cleans up. (But it is also easy to write code that
always cleans up - except if the program wa killed by SIGINT/SIGTERM.)

Maybe there is some other solution to this problem that I'm missing...
