atexit is a way to create a stack of functions that are called when a program
exits.

my guess is since it's a door library (and they don't necessarily control the program flow, the door programmed with it does) they want to ensure if the door game just abruptly decides to do exit(), odoors can at least clean up after itself.

the other option would be to make the door programmer responsible for it.. they'd call the atexit()-ed functions themselves when they're finishing up.
