Currently we have

• Proof of concept runner that works with Tornado, and inside the notebook, and with the dask distributed client.
• Proof of concept runner that works with asyncio, and inside the notebook, but not in the notebook with the distributed.asyncio.AioClient
  • asyncio runner requires an event loop integration to work in the notebook. An MR was just merged that includes the integration
    into the ipykernel itself, but for now we can also include the (relatively small) snippet into this project. All that is required from users is to execute %gui asyncio from the notebook
  • The coroutine that creates the AioClient hangs on await AioClient(). The distributed codebase is pretty easy to read, so this can probably be solved.

I'm going to close this for now, although there still appear to be stability issues when coroutines are still running and we try to restart the kernel
