This was fixed long ago; here once again is the correct code from
/sys/sys/sys_generic.c$selwakeup():

selwakeup(p, coll)
	register struct proc *p;
	int coll;
{

	if (coll) {
		nselcoll++;
		wakeup((caddr_t)&selwait);
	}
	if (p) {
		int s = spl6();
		if (p->p_wchan == (caddr_t)&selwait) {
			if (p->p_stat == SSLEEP)
				setrun(p);
			else
				unsleep(p);
		}
		else if (p->p_flag & SSEL)
			p->p_flag &= ~SSEL;
		splx(s);
	}
}
