+missing bootmain.c from printout
+funny \ alignment in mmu.h
+
+main.c:
+	should use static int bcpu to avoid having live
+	stack variable across the asm volatile that 
+	changes %esp and %ebp.
+
+init.c:
+	should while(wait() >= 0);
+	not just wait();
+
+proc.c:
+	comment at top of scheduler() should say
+		via longjmp back to the scheduler
+	not
+		via longjmp back to the top of scheduler
+
+	sched should panic if state == RUNNING.
+
+	forkret comment should say "Return" not "return"
+	
+	as a consequence of the implementation of proc_kill,
+	any loop calling sleep should check for p->killed
+	and be able to break out with an error return.
+
+	can swap procdump up after proc_kill
+	and then have proc_exit and proc_wait on same sheet
+
+	proc_exit should wake up proc[1] if any
+	reparenting was done.
+
+trap.c
+	if spin locks are ever held without cli,
+	trap should call yield() only if nlock == 0
