Ooo.  Well, if we *could* lay the groundwork for a newer stat()
routine in time for 6.0, then I'd really like to see that.  The
first time I read this message I thought you were saying "it IS too
late...", which would have been understandable.

There are a number of other fields in 'struct stat' that people have
wanted to see expanded.  But I'm not sure if that's what you meant by
your question of "anything else to get bumped?"
