Let me reword the issue in a different way.

>From queue.h:
#define TAILQ_FIRST(head)       ((head)->tqh_first)

#define TAILQ_REMOVE(head, elm, field) do {                             \
        if ((TAILQ_NEXT((elm), field)) != NULL)                         \
                TAILQ_NEXT((elm), field)->field.tqe_prev =              \
                    (elm)->field.tqe_prev;                              \
        else                                                            \
                (head)->tqh_last = (elm)->field.tqe_prev;               \
        *(elm)->field.tqe_prev = TAILQ_NEXT((elm), field);              \
} while (0)

The TAILQ_REMOVE macro does not touch tqh_first, so how can
	while((acmd = busyq->tqh_first) != NULL) { // macro written out
possibly stop when the loop does not alter the value busyq->tqh_first?
