  GR doesn't predict black hole evaporation. It's those quantum mechanists
messing around.

  Thinking about it, this is probably what would happen:

  If we assume the mass of the black hole would decrease, then the EH would
recess. The photons which were emitted extremely close to the EH will get
a speedup when the EH recesses. Basically the "point of entry" will stop
being *at* the EH and becomes being *above* it. Thus all the photons will
reach the external observer in finite time. The external observer will
end up actually "seeing" the falling object cross the EH.

  After all, how would the external observer actually see the black hole
getting smaller?

  I don't think that's possible. When he is exactly at the EH, the entire
EH engulfs the entire view on all sides. He doesn't see anything else
than the EH. What he "sees" inside... I don't know.
