* The first value is the number of times the gc has been inserted / removed.
* Inserted is set to true when called with a gc inserted, set to zero otherwise.
* Reboot value is changed on every reboot.
*
* Calling this func more than once results in strange values returned.
*
* The reboot value becomes zero if called again with a gc inserted.
* The value is something different when called again without a gc inserted.
* Sometimes the inserted value is set to one if called again and the gc isn't inserted.
*
* Overall, idk what this func does.
