  Log:
  Make sure that we refresh the PID on read(2) and write(2) operations.
  This fixes the process portion of the bpf(4) stats if the peer forks
  into the background after it's opened the descriptor.  This bug
  results in the following behavior for netstat -B:
  
  # netstat -B
    Pid  Netif  Flags      Recv      Drop     Match Sblen Hblen Command
  netstat: kern.proc.pid failed: No such process
