  Modified files:
    sys/kern             kern_exit.c 
  Log:
  - Slightly reorder the events around the setting of PRS_ZOMBIE to be less
    hokie and much more readable and expand the comment to explain why it is
    the way that it is.
  - Close a race where one CPU could free the process belonging to a thread
    on another CPU that hasn't quite finished exiting yet but is beyond the
    point of setting the process state as PRS_ZOMBIE.
