WebMDS uses boost::pool's malloc() and free() instead of ordered_malloc() and ordered_free(), hence the unused memory is not ordered in most time. I did some tests with ordered_malloc() and ordered_free() by replacing malloc() and free() on MDS, but the performance is too bad. Then I tried to use tcmalloc directly without boost::pool on MDS.
