Comment (by stephen):

 If the code currently uses shared pointers, it is less of a change to pass
 a reference to the pointer through - just add an ampersand to the argument
 type in the method signature.  (I think we should do this everywhere -
 although we've discussed this in the past.) However, it is probably
 clearer to dereference the pointer and pass the reference to the object
 through to the internal method.
