I'd like to commit the code to keep the ucred across userland,
with the code to clear it to NULL kept under DEBUG ifdefs.
i.e.
> in trap(), ast() and syscall()
>
> if (td->td_ucred != p->p_ucred) {
> PROC_LOCK(p);
> if (td->td_ucred) {
> crfree(td->td_ucred);
> td->td_ucred = NULL;
> }
> if (p->p_ucred != NULL) {
> td->td_ucred = crhold(p->p_ucred);
> }
> PROC_UNLOCK(p);
> }
and in userret() and ast()
>#ifdef DEBUG /*your choice of variable here*/
> PROC_LOCK(p);
> if (td->td_ucred) {
> crfree(td->td_ucred);
> td->td_ucred = NULL;
> }
> PROC_UNLOCK(p);
>#endif
