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?malloc is the primary target I believe. Saves lots of memory to keep caches per CPU rather than per thread.
Agreed, a competent default malloc() in glibc would be a very nice change
from the current state.
