    sys/kern             kern_condvar.c kern_switch.c kern_synch.c 
    sys/sys              proc.h 
    sys/vm               vm_glue.c 
  Log:
  - Optimize wakeup() and its friends; if a thread waken up is being
    swapped in, we do not have to ask for the scheduler thread to do
    that.
  
  - Assert that a process is not swapped out in runq functions and
    swapout().
  
  - Introduce thread_safetoswapout() for readability.
  
  - In swapout_procs(), perform a test that may block (check of a
    thread working on its vm map) first.  This lets us call swapout()
    with the sched_lock held, providing a better atomicity.
