Interrupting kills the kernel

[davidbrochart]

See jupyter/jupyter_client#754.

Run this code in Jupyter Lab with a xeus-python (not raw) kernel:

import asyncio

async def main():
    await asyncio.sleep(5)

await main()

and interrupt the execution before the execution completes. You should see "Kernel Restarting".

Actually this is not related to top-level await, the kernel dies even while interrupting this:

import time

time.sleep(100)
