  Modified files:
    sys/kern             kern_exit.c 
  Log:
  - Always use the proc lock of the task leader to protect the peers list of
    processes.
  - Don't construct fake call args and then call kill().  psignal is not
    anymore complicated and is quicker and not prone to locking problems.
    Calling psignal() avoids having to do a pfind() since we already have a
    proc pointer and also allows us to keep the task leader locked while we
    kill all the peer processes so the list is kept coherent.
  - When a kthread exits, do a wakeup() on its proc pointers.  This can be
    used by kernel modules that have kthreads and want to ensure they have
    safely exited before completely the MOD_UNLOAD event.
