    SubjectRe: [profile] amortize atomic hit count increments

    William, any reason not to fully per-cpu the profile buffer
    and then only traverse the array when the user attempts to
    capture the counters?

    Then we can undo the atomics altogether, as well as the cacheline
    traffic, for the extremely common case.

    Are there space concerns?
