    sys/kern             kern_proc.c kern_prot.c 
  Log:
  Clean up breakage in inferior() I introduced in 1.92 of kern_proc.c:
  - Restore inferior() to being iterative rather than recursive.
  - Assert that the proctree_lock is held in inferior() and change the one
    caller to get a shared lock of it.  This also ensures that we hold the
    lock after performing the check so the check can't be made invalid out
    from under us after the check but before we act on it.
