New submission from Xiang Zhang <angwe...@126.com>:
A simple snippet:
import threading
def func():
while True:
print(1,2,3,4,5,6,7,8,9,10)
t1 = threading.Thread(target=func)
t2 = threading.Thread(target=func)
t1.start()
t2.start()
Running this snippet and Ctrl-C raises FatalError:
^CException ignored in: <module 'threading' from
'/root/Python-2.8.1/Lib/threading.py'>
