Modified files:
        sys/kern       : kern_exit.c 

Log message:
Fix wait4 to not modify status or rusage if we return 0 because of
WNOHANG, in accordance with POSIX.  Additionally, if rusage is
requested but the waited-on process did not terminate, return zero
bytes instead of kernel stack garbage.

ok deraadt, millert
