Well I have seen such evidence a couple of times. Some profiling of code using huge library stacks gave really surprising results. I think it's worth considering that there's no such thing as "microsecond spent on few commands" alone. Every extra vm command competes with others in the cpu cache, similar for classes loaded in the os file cache. It seems to matter when you have thousands of typical calls on a stack instead of, say, dozens.
