    If these numbers are with your "if (ksoftirqd_pending()) return;" thing
    at the top of do_softirq() then I must agree with you.

    Otherwise, keep in mind what I said, and also as Robert mentioned every
    single local_bh_enable() is going to call do_softirq() if the count falls
    to zero.
