 One limitation of the cache compensated timer is that the task that benchmarked functions should be pinned to a core. This is due to each core having its own event counters that are independent of each other. For example, if ``ccomp_timer_start`` gets called on one core, put to sleep by the scheduler, wakes up, and gets rescheduled on the other core, then the corresponding ``ccomp_timer_stop`` will be invalid.
