when oobabot enabled, restarting text-gen hangs

[chrisrude]

When the oobabot extension is loaded, go to the "Interface mode" tab and choose "Apply and restart the interface"

This will hang, rather than reload the interface.

What's happening is gradio is waiting for its update task for the html log to finish, but it is designed to run indefinitely.

It won't notice the request to exit because gradio's looper there is using sleep, rather than asyncio.sleep.

Either find a workaround here, or land a fix in gradio.
