Simple case not working

[aranvir]

Hi benny, first of all thank you for the great work! I have been looking for a while now for a way to gracefully shutdown asyncio scripts and was very glad when I found your project and the extensive explanations.

However, I encountered some problems (all with python 3.7 on windows 10):

• There are some =-signs just floating around in the code (in logging calls).
• The simple case cannot be interrupted after start. During start and stop your solution works fine but once it is in the wait part of the loop I cannot interrupt it. The complex script works fine as well.
