      Description


      When using the new -Xhprof:{net,file} option when one hits ctrl-scrolllock
      or ctrl-\ to take a dump the dump can take a very long time and the user
      is stuck with the messgae :-
      "Dumping Java heap and allocation sites ... "
      Since all threads are suspended it's unclear to user if the application
      is hung or if there is something really happening.

      It would be nice to have a "." printed periodically while the dump file
      is begin created. HAT does this when it is chasing the references and
      it would be nice if -Xhprof did the same.
