Marco Paolini added the comment:
KeyboardInterrupt is not handled gently by asyncio (see
https://groups.google.com/d/msg/python-tulip/sovg7EIBoXs/m7U-0UXqzSQJ)
you could cancel all tasks in the signal handler:
...
def sig_interrupt():
print('interrupt')
for task in asyncio.Task.all_tasks():
task.cancel()
loop.add_signal_handler(signal.SIGINT, sig_interrupt)
...
