Shit.  My local machine has BSD4.4-Lite2 integrated... sorry. 8-(.

Which code, exactly, are you running?

For your code, this might need to be:

>   	if (freevnodes < (numvnodes >> 2) ||
>   	    numvnodes < desiredvnodes ||
> ! 	    vp == NULL ||      /* list empty */
> ! 	    (vp->v_usecount && vp->v_usage == 0))    /* queue wrapped */
> !         {

Damn, I'm getting old.
