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.
