psutil.NoSuchProcess when restarting the kernel

See original GitHub issue

Description

What steps will reproduce the problem?

import turtle as tt

def draw_square():
    window = tt.Screen()
    window.bgcolor('light blue')

    pony = tt.Turtle()
    pony.speed(1)
    pony.forward(100)
    pony.right(90)

    window.exitonclick()

draw_square()
tt.bye()

This script will have no response while the second time I run it.
