So, I have looked at that, and at the end concluded that Andres'
suggestion to use PGAlignedBlock in pg_write_zeros() will serve better
in the long run.  Thomas has mentioned upthread that some of the
comments don't need to be that long, so I have tweaked these to be
minimal, and updated a few more areas.  Note that this has been split
into two commits: one to introduce the new routine in file_utils.c and
a second for the switch in walmethods.c.
