Well, then how should we do database access ? Because without that part sorted out the rest of the framework is unusable. Incidentally, my personal opinion is that is the reason why we don't have massive adoption of asyncio despite lots of frameworks (like apistar). Nodejs for example has every database driver as asynchronous. It is probably worth the effort to make a asyncio compatible dB layer.
