How low is ``low''? The lowest possible frame address is 0x1000, I guess (for a hypothetical architecture which leaves only the null page uncommitted and has its stack right after that). Is it unreasonable to expect 4K frames? I don't think so; I once had to debug a program with infinite recursion, where I needed to wade through 750K(!) frames. As another data point, Emacs during garbage collection routinely uses 10K or more recursive invocations of mark_object function and its ilk.
