I know the "values" struct is doing exactly this, but I suspect it's
abusing the vtable system.  I suspect that what scm_init_stacks() in
stacks.c is doing is normal (if there's such a thing as "normal").

Perhaps we have an expert lurking here, but I think make-vtable-vtable
does in fact do what its name suggests: make a vtable for creating
vtables.
