I think the undesirable part of this name is "module" ;-)

At least, AFAICT, while this feature is introduced so that modules can
use it, it is not directly dependent on modules.

So, we could call it something else like "Lisp_Opaque_finalized_Object"
(I'm sure you can all easily come up with an even longer name).

It means "the natural size of things on the particular system".

Right, so "words" are 64bit on such a system.
