By default, objects created through `PARSEC_OBJ_NEW` will be free'd in the callback, objects constructed through `PARSEC_OBJ_CONSTRUCT` will only be destructed. Users/applications can provide their own release callback through `PARSEC_OBJ_RELEASE_CONSTRUCT`. Mempools break the PaRSEC object model. To store the mempool origin, a list item and an offset stored in the mempool that points to the mempool from where the item was allocated. We should consider adding a type `parsec_mempool_item_t` that stores the origin mempool. Then the release callback invoked from `PARSEC_OBJ_RELEASE` can put the object back into the mempool. Yes, this adds 8B to the `parsec_object_t` but in today's world that is negligible and is outweighed by the benefits of having a more flexible object model.
