Doh!  This is what I get for not going back and looking at the draft.
You're right that my objection was in terms of determining the
out-of-orderness and not determining the extent or the characteristics
this dynamic created.  I do support the use of time for characterizing
reordering events, just not for determining the event.  But, somehow I
misread the context of Bert's note.  In any case, sorry for the spurious
chud.  I'll shut up now! :)
