 * test file access by communicator besides COMM_WORLD.

 * Split COMM_WORLD into two, one (even_comm) contains the original

 * processes of odd ranks.  Processes in even_comm creates a file, then

 * cloose it, using even_comm.  Processes in old_comm just do a barrier

 * using odd_comm.  Then they all do a barrier using COMM_WORLD.

 * If the file creation and cloose does not do correct collective action
