| Title | Restrictions on maximum pool alignment are not checked or documented |

| Description | The MV, MVFF, and MVT pool classes offer the MPS_KEY_ALIGN keyword for setting "the alignment of addresses for allocation (and freeing)". MVT and MVFF document a minimum, but no maximum alignment. In fact, the MPS will not honour requests for alignment greater than the arena grain size, because there is no interface to allocate from the arena with an alignment. |
| Analysis | Document the restriction and its relationship to MPS_KEY_ARENA_GRAIN_SIZE. Check requested alignments. |
| How found | inspection |
| Evidence | MVFFExtend amongst others make no attempt to align. |
