Hmm, do we want injection_points module to be a dumping ground for 
callbacks that are only useful for very specific injection points, in 
specific tests? I view it as a more general purpose module, containing 
callbacks that are useful for many different tests. Don't get me wrong, 
I'm not necessarily against it, and it would be expedient, that's just 
not how I see the purpose of injection_points.

Ok, I kept it that way.

Fixed.

Fixed.

Committed, thanks for the review, and thanks Jacob for the testing!
