I guess this would mean that for each method that talks to the database 
there should be an async version, i.e. instead of

     def print_foo():
         cursor.execute("select * from foo")
         for row in cursor:
	        print(row)

we could do:

     async def print_foo():
         await cursor.execute("select * from foo")
         async for row in cursor:
             print(row)

Then we could use cx_Oracle with other async frameworks (aiohttp, sanic 
and probably Tornado and Twisted and a bunch others) and take advantage 
of cx_Oracle's new async features.

(We can use cx_Oracle with these frameworks now, but during any calls to 
the database the code can do nothing else except wait for the answer 
from the database).

Details for async/await are in PEP 492 at 
https://www.python.org/dev/peps/pep-0492/
