  SVN rev 216353 on 2010-12-10 10:48:54Z by kib
  
  MFC r216150, r216158:
  If unix socket has a unix socket attached as the rights that has a
  unix socket attached as the rights that has a unix socket attached as
  the rights ... Kernel may overflow the stack on attempt to close such
  socket.
  
  Only close the rights file in the context of the current close if the
  file is not unix domain socket. Otherwise, postpone the work to
  taskqueue, preventing unlimited recursion.
