   ...  Just try tripping the shutter at the highest shutter speed to
   see if there is an obvious delay beyond the 1/1000.  At that speed
   the mirror should be up and down at 1/1000 of a second, generally
   speaking.

Ted, I don't think this is actually true.  The mirror is much more
massive than the shutter, and it would take a lot of energy to flap it
back and forth as quickly as the shutter.  I don't really know how
quickly it goes up and down, but I'm sure it takes much longer than a
millisecond -- probably 100 milliseconds or more for the whole cycle.
