[FIXED] Why does the asyncio's event loop suppress the KeyboardInterrupt on Windows?

Issue

I have this really small test program which does nothing apart from a executing an asyncio event loop:

import asyncio
asyncio.get_event_loop().run_forever()

When I run this program on Linux and press Ctrl+C, the program will terminate correctly with a KeyboardInterrupt exception. On Windows pressing Ctrl+C does nothing (tested with Python 3.4.2). A simple inifinite loop with time.sleep() raises the KeyboardInterrupt correctly even on Windows:

import time
while True:
    time.sleep(3600)

Why does the asyncio's event loop suppress the KeyboardInterrupt on Windows?

Solution

This is a bug, sure.

See issue on python bug-tracker for the problem solving progress.
