  Modified files:
    sys/kern             kern_kthread.c 
  Log:
  - Use _PHOLD and move it before a PROC_UNLOCK to reduce the number of
    mutex operations in kthread_create().
  - Lock a kthread's proc before changing its parent via proc_reparent().
  - Test P_KTHREAD not P_SYSTEM in kthread_suspend() and kthread_resume().
    P_SYSTEM just means that the process shouldn't be swapped and is used
    for vinum's daemon for example.
  - Lock all the signal state used for suspending and resuming kthreads with
    the proc lock.
