Benchmarking various approaches for reading the current CPU number:
So I'd like to see the benchmarks of something that actually *does* something.
IOW, what's the bigger-picture "this is what it actually is useful
for, and how it speeds things up".
Nobody gets a cpu number just to get a cpu number - it's not a useful
thing to benchmark. What does getcpu() so much that we care?
We've had tons of clever features that nobody actually uses, because
they aren't really portable enough. I'd like to be convinced that this
is actually going to be used by real applications.
