You should be aware that call to Qgis C/C++ api from Python hold the GIL
and may prevent custom python threads to run.

Hi David,
I suspected this much. In theory, I can move the event loop into a
separate thread [1, 2] - this should allow QGIS' event loop to continue
running and accepting input etc. I am *guessing* that this can be made
work. Question: Has someone around here actually tried it before?
Best regards,
Sebastian

Hi,
Asynchronous python code with asyncio assume that you have an ioloop
running in a blocking way in your python code:
that means that no other code (in the same thread) cannot run
concurrently with your async tasks while your loop is running.
