nit: Do you ever set these separately? IF you always set them as a pair, why not
have one function:

SetInterceptFunctions(...)

Done.  I kept individual functions since I often use them locally.

It was not clear which of these should be set first, and it was not clear if it
mattered.  Using a single function allows you to encapsulate the ordering of the
sets in your module.

The individual functions should not be public, but you are free to use them as
private methods to assist in your implementation.

Ok, I'll remove individual functions.  When I need individual functions locally,
I add them locally.

Done.
