+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
