be a few bits left to clean from the HARP code in terms of what is using the storage pools; once that's done, the memory management code can be removed entirely. This commit effectively changes the use of dynamic memory routines from atm_allocate, atm_free, atm_release_pool to uma_zcreate, uma_zalloc, uma_zfree, uma_zdestroy.
