   // Note: This server assumes that the client will reset the histogram
   // after each upload to simplify the merging.

   // This server can accept connections while handling currently open connections.
   // Compare this script to hserv.C that blocks on accept.
   // In this script a server socket is created and added to a monitor.
   // A monitor object is used to monitor connection requests on
   // the server socket. After accepting the connection
   // the new socket is added to the monitor and immediately ready
   // for use. Once two connections are accepted the server socket
   // is removed from the monitor and closed. The monitor continues
   // monitoring the sockets.
   //

   //   - Open three windows
