[PATCH 1 of 3] demandimport: pass proper level to __import__ in Python 3

[Pierre-Yves David]

Ok, new (softer) rule you need to learn about: Avoids having too many in 
flight.

You already have 3 series currently in review. sending more series (even 
unrelated) are not going to help.

There is two actions you can take to help here:

1. applying feedback you received on your series (or replying to 
question asked)
2. Doing some review yourself.
