Basically, sort a list of integers by spawning a new thread or process for each element then sleep for the value of that element then print out that element. Here’s the original bash example, but I’d love to see other crazy languages.

#!/bin/bash
function f() {
    sleep "$1"
    echo "$1"
}
while [ -n "$1" ]
do
    f "$1" &
    shift
done
wait
