Opening the same file multiple times will yield different fds, and the paths can be modified independently of the fd.
The goal here is to find if:
1. there are new input devices
2. which are joysticks (a category which, for SDL, includes gamepads, so basically "has the user plugged in a new gamepad they might want to use for the game")

How would keeping a bunch of fds around help?
