  Log:
  Drop Giant and acquire the UNIX domain socket subsystem lock a bit
  earlier in unp_connect() so that vp->v_socket can't change between
  our copying its value to a local variable and later use of that
  variable.  This may have been responsible for a panic during
  shutdown that I experienced where simultaneous closing of a listen
  socket by rpcbind and a new connection being made to rpcbind by
  mountd.
