Log Message:
cpu_switch:
* return `switched to same process' only if that process was actually
  already on a run queue when we entered.
* skip the switch to the idle stack if we can switch immediately
* .. and because of this, don't release the scheduler lock until after
  we've fully switched to the new process's stack.
