Well, both Clang [0] and GCC [1] do compile the "insanely-recursive" fib into something less insane (or, in case of GCC, something that's insane in a different way). It looks like it's done with partial unrolling/inlining? And, well, if you disregard heavy optimizations, then this "insanely-recursive" function is actually a somewhat decent way to measure the efficiency of the function calls and arithmetic.
