Hi Thomas,

I've been seeing these on and off for a while now.  They don't
seem to affect anything but perhaps I should track them down?

Do you know what it means?  (I'm asking you because evidently
debugobjects.c is from you?  I read the good explanation in the
changelog of 3ac7fe5a, but it didn't clue me into what's going
on. ;-)

Thanks,
Mike
