 * Mempool
 * =======
 *
 * #. Basic tests: done on one core with and without cache:
 *
 *    - Get one object, put one object
 *    - Get two objects, put two objects
 *    - Get all objects, test that their content is not modified and
 *      put them back in the pool.
 *
 * #. Performance tests:
 *
 *    Each core get *n_keep* objects per bulk of *n_get_bulk*. Then,
 *    objects are put back in the pool per bulk of *n_put_bulk*.
 *
 *    This sequence is done during TIME_S seconds.
 *
 *    This test is done on the following configurations:
 *
 *    - Cores configuration (*cores*)
 *
 *      - One core with cache
 *      - Two cores with cache
 *      - Max. cores with cache
 *      - One core without cache
 *      - Two cores without cache
 *      - Max. cores without cache
 *
 *    - Bulk size (*n_get_bulk*, *n_put_bulk*)
 *
 *      - Bulk get from 1 to 32
 *      - Bulk put from 1 to 32
 *
 *    - Number of kept objects (*n_keep*)
 *
 *      - 32
 *      - 128
