... and perhaps I should add that, under certain circumstances, perhaps it
should be possible to just mov four bytes from memory and ignore one of the
bytes. On platforms where access must be aligned that would be more difficult
to support consistently; and there may be end-of-page issues etc. Still, it's
not inconceivable.
