I will change the test to do nothing on single-cpu systems.

I think it is mutli-core, not multi-cpus. But i'm not quite sure whether such differences(multi-cores vs multi-cpus) will affect golang code or not.
Anyway, thank you, you are a good guy. I got the result when run with -benchtime=1s
$ go test -v -benchtime=1s

It seems it changes a bit when have different benchtime...maybe there should be a ratio to point out the trust number...
But i still miss the feature that can Sizeof a procedure/function in runtime ;)
trust_number, size, ok = unsafe.Sizeof(func() {
sum := []int{1,2,3,4,5,6}
})
It is cool.
The benchmarks time vary from run to run, so the greater X is in
"-benchtime=Xs" the more consistent the results will be.
For the purpose here, though, it seems unimportant because in the lengths
where the results are close, then either choice is a good one.
I changed the code at github to be more defensive about single-processor or
"GOMAXPROCS=1" systems.
Good luck!
