Leave it to me to find public scoped privates to use in my code. :P But you're right, the comments beside the function names did state that they were used only for unit-tests. So with that thought, they were clearly meant to be privates based on the comments alone.

Phew! I'm glad they don't need to be retained, hopefully no-one else was 
bitten by that bug.
