The strange thing [to me] is that, in a discussion of stack allocation patterns, sbrk is a deeply confusing red-herring. 'Little-s' stacks require bulk-allocated pages that are then carved up into object allocations as required, and de-allocated in last-in-first-out ordering. No alloca or sbrk required.
