I didn't provide results with less_stack.patch because they were almost the same, just 1-3% faster. That might be just a random noise or compiler artifact. But may be an effect of inlining call_function(). Could you run full Python benchmarks? Decreasing the size of small stack doesn't impact a performance in these cases, but may impact a performance of calls with larger number of arguments. AFAIK the size of some small stacks already was decreased from 8 to 5.
