  Modified files:
    sys/kern             kern_fork.c 
  Log:
  - Lock the forklist with an sx lock.
  - Add proc locking to fork1().  Always lock the child procoess (new
    process) first when both processes need to be locked at the same
    time.
  - Remove unneeded spl()'s as the data they protected is now locked.
  - Ensure that the proctree is exclusively locked and the new process is
    locked when setting up the parent process pointer.
  - Lock the check for P_KTHREAD in p_flag in fork_exit().
