 There should be no busy-waiting in any of your solutions to this

-interrupts in your solution by calling @func{intr_disable} or
-@func{intr_set_level}, although you may find doing so to be useful
-while debugging.  Instead, use semaphores, locks and condition

 Given some designs of some problems, there may be one or two instances
 in which it is appropriate to directly change the interrupt levels
