Ouch. I think you are right with the assumption about the deep nesting. We have 
an unbounded recursion here... which should not be. We have to move the 
required stack onto the heap. Regarding wget 1.x, I assume it takes less stack 
space per recursion and thus succeeds (but the problem can still happen with 
deeper nesting).
