somebody dropping something on some sitting-duck climber below him in

the bottom.
It is true that multiple climbers directly in a line is
dangerous, but if one is rigging with multiple climbers in mind, then
the route can deviate to the side a bit at each rebelay. Such a
system avoids having people directly above the rebelays below them
when climbing, removing the danger. Of course by the time one placed
dozens of rebelays in a single pit the route would have deviated a
lot, possibly spiraling all the way around back under itself! That's
not a common problem, however. ;-)
