Thanks for looking at it!

Please find attached v12, with more comments and comments changes to explain the multiple cases (for safety) and phases (for efficiency).
Is it worth mentioning that pg_memory_is_all_zeros does not work correctly on 32-bit systems?
(63 < (size_t) * 8) /* 63 - 32*/
Or do we adjust magic constants according to 32/64 bit?
