  I'm obviously talking nonsense below.  Sorry.

  The real explanation is that they are put on a runqueue when executed:

        if (TD_AWAITING_INTR(td)) {
                CTR2(KTR_INTR, "%s: setrunqueue %d", __func__, p->p_pid);
                TD_CLR_IWAIT(td);
                setrunqueue(td);
                if (do_switch &&
                    (ctd->td_critnest == 1) ) {
...

  Sorry again!

  Not always.  They have to be put on a runqueue if they block on a
  mutex, say.
