A crazy tool to find out stack size.

fn crazy(level: usize, kb: &mut [u8]) {
    const SIZE: usize = 1000;

    if kb.len() > 0 {
        let len = kb.len();
        kb[len / 2] = level as u8;
    }
    println!("level: {}", level);
    let mut one_kb: [u8; SIZE] = [0; SIZE];
    crazy(level + 1, &mut one_kb);
}
