The consequences is that 'cleanup_ns()' will try to delete an invalid netns, and wait 20 seconds if the netns list is empty. Instead of just checking if the name is not empty, convert the string separated by spaces to an array. Manipulating the array is cleaner, and calling 'cleanup_ns()' with an empty array will be a no-op.
