  Modified files:
    sys/kern             kern_ktrace.c 
  Log:
  If multiple processes are being traced and some other process has a write
  error, the vnode ref that we rely on from p_tracep can get ripped out from
  under us, causing a panic.  vref() a the ktrace vnode for the duration of
  the write rather then relying on the ref from p_tracep.
