A quick, simple question about pseudo-vectors... Is there a guarantee
that once allocated, a pseudo-vector object will not be relocated in
memory during its life cycle?

Yes, because the Emacs garbage collector doesn't relocate objects.

But ralloc.c does (on systems that use it). However, pseudo-vectors
are not relocated, because they are not large enough to bother.
