    There were still a couple complaints about C3 failing, possibly on older
    laptops only. However, since the failure case is a hang or poor runtime
    behavior, I thought it would be better to be safe and disable both C2
    and C3 for the release. If we can nail down the problem laptops, it
    will be re-enabled. For now, if you're using this, re-enable it in
    rc.conf with something like:

    performance_cx_lowest="LOW"
    economy_cx_lowest="LOW"
