I am not sure I followed everthing here.  Do you want me to post my last
patch without Chuck's additions or should I wait, get Chuck's changes
and then post the entire patch.  It sounds like we need to check in my
changes and Chuck's changes together in one patch so I am assuming I
should wait for those and then post the whole thing.
