    The 'Load average' value is mostly meaningless.
    It includes any process/thread that is sleeping uninterruptably - even
    if the process is never woken (or is only woken for short periods).

    If you have a kernel thread that you don't want affected by signals
    (exits on some request to the driver) then you end up increasing the
    'load average'.
