neutronium as a material for his thought experiment. I can design a black hole where g for a spherical shell at r=2M + dr, dr=1meter, is g(Earth). In other words if you were in a ship with rockets firing, remaining at rest with respect to the event horizon, at r=2M + 1meter you would weigh the same as you do standing on the surface of the Earth. Granted a very large black hole. For a freely falling astronaut no effects (tidal stretching) would be felt until very far inside this black hole because tidal stretching equaling g(Earth) won't occur until d(tau)=.31 second before the astronaut is crunch at the singularity. I'm just guessing (havn't worked out the details) that d(tau) (wristwatch time for the freefalling astronaut) for a whole that large would be ~50 Earth years from event horizon to crunch at the singularity.
