Hi Adam,Thanks for the links.  These are simply exposing the functions as a
formal a API's.  I understand that you typically don't want to change
externally exposed API's but these can easily be stubbed out (or removed).
I should have pointed out in my original email that I have tried to remove
these API's and I can still run all the WebKit/Mac tests fine.  So at least
two things are missing (IMHO) - tests that verify that this functionality is
working as intended and documentation to tell what that intent is.  But this
is only required if somebody is actually using these functions...
