 * This test may be used to confirm that memory is properly recovered from
 * freed datatypes.  To test this, build the MPI implementation with memory
 * leak checking.  As this program may be run with a single process, it should
 * also be easy to run it under valgrind or a similar program.  With MPICH,
 * you can configure with the option
 *
 *   --enable-g=mem
 *
 * to turn on MPICH's internal memory checking.
