This should be in the header file (After adding DISALLOW_COPY_AND_ASSIGN to the
URLRequestMockHTTPJob class)

Done. Should have read your comment more carefully.

IMPORTANT:  Remove the &.  Otherwise, we'll have a reference to the
scoped_refptr owned back the callback object, which is destroyed once the
callback has been run and then deleted.

Done.
