  Log:
  In sonewconn(), set the new socket's state to show the protocol-provided
  connection status before inserting the new socket into the listen
  socket's accept queue, or there might be a race in which another thread
  wakes up when the accept lock is released, and sees the socket before its
  state is set correctly.  The wakeup still occurs after the accept lock is
  released.  There have been no diagnoses of this bug in real-world systems
  (as yet).
