True. And I meant to suggest that, on average, we'd get the same 1 
second delay (if we assume all positions in the file are equally probable).

However, I've just tried the same experiment without goto-char, and got 
essentially the same result as with it: 1.2 s (my previous result was 
with "cold" filesystem cache).

In addition to that, though, I think this call returns before the window 
finishes displaying. So, when point is at eob, there's some extra wait, 
but I'm not sure how to measure it.
