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.
