    One can run the date call even while ntpd keeps running.

    It looks like is not affected (on a system where ntpd is
    running). That is to say, at least the mysqld instance on such a system
    did not jump to high CPU usage. I did not try your testcase.c there,
    since that would likely freak out the webapps - or the management.

    Other reports on IRC include that 2.6.32-71.el6 (RHEL) is affected.
    (Backporting gone wrong, *snicker* ;)
