  Log:
  SVN rev 194460 on 2009-06-18 20:56:22Z by jhb
  
  Fix a deadlock in the getpeername() method for UNIX domain sockets.
  Instead of locking the local unp followed by the remote unp, use the same
  locking model as accept() and read lock the global link lock followed by
  the remote unp while fetching the remote sockaddr.
