+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
