Okay, thanks.  Your comments seem to be focused on my patch and not so much on
this problem that was exposed by it.  I realize I invited those comments with
my response and do want to continue to have that discussion, but I want to have
it separately from this issue.  Here I'd like to get a confirmation of just the
NOTE_DATA problem so I can prepare patch for it.
