  BUG#11132 Connections stuck in CLOSE_WAIT
  
  This fixes the problem in 5.0 in the correct way.
  
  The previous patch (for 4.1) is only valid for 4.1 and is done at the right time
  for 4.1.

    The ndbd angel process keeps the mgm connection open as it retains a reference
    to the socket.
    
    this means that when the mgm server is killed, the socket stays in CLOSE_WAIT 
    (the ndb process will close() it okay in 5.0, as we reused it for a transporter
    but this isn't enough as the angel process still has a reference to that socket).
    
    so, by adding in a theConfig->closeConfiguration(); in the angel process, the ndb
    process is left with the only reference to the socket - which it can close whenever
    it likes (namely when the connection is terminated).
