Spyder: psutil.NoSuchProcess when restarting the kernel
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.

THIS SCRIPT WILL HAVE NO RESPONSE WHILE THE SECOND TIME I RUN IT.
Please stop using caps in your next messages. That's considered rude and not due to that we're going to help you faster.
