Brent, Liz and Jesse, OK, now I understand the effect you guys are referencing...
I thought Jesse had been saying that things don't ACTUALLY fall into black holes, they just pile up on the event horizon surface, because their motion actually slows down as they approach the surface BECAUSE their clocks slow down from the intense gravity. That of course is incorrect. But of course things actually DO fall into black holes continuously accelerating as they do so. Otherwise black holes could never form, could not exist, and we would not be observing them.. But I see now what you guys are referencing is just how it appears to an outside observer as the falling object approaches c as it nears the event horizon. So, given that I stand corrected!
