Many parts of the kernel have this problem and use:

	struct proc *p = curproc;	/* XXX */

(this makes passing the parameter around to other places mainly a waste
of time :-().  See e.g., slopen() in if_sl.c.  The proc parameter got
lost a couple of layers above.

I wonder how often p != curproc in suser().
