Interesting.
As Michael suggested this works, mostly:
from time import sleep
def loop():
x = 0
while 1:
print "x:",x
x += 1
sleep(0.5)
if __name__ == "__main__":
while 1:
try:
loop()
except KeyboardInterrupt:
print "Nope, not going to stop."
Ctrl-C is ignored. But on Win XP, at least, Ctrl-Break still exits the
program.
