Thanks for that. Fascinating discussion between you and GvR.

Reading it gave me an idea.

Run the database handler in a separate thread. Use a queue.Queue to send 
requests to the handler. Use an asyncio.Queue to send results back to the 
caller, which can call 'await q.get()'.

I ran a quick test and it seems to work. What do you think?
