    hm, the IPI sending and receiving is nicely paired up:

    [ 625.795008] IPI (@smp_reschedule_interrupt) from task swapper:0 on CPU#1:
    [ 625.795223] IPI (@native_smp_send_reschedule) from task amarokapp:2882 on CPU#1:

    amarokapp does wake up threads every 20 microseconds - that could
    explain it. It's probably Xorg running on one core, amarokapp on the
    other core. That's already 100 reschedules/sec.
