Well, I was under the impression that `package-suppress' would
completely suppress a given library in the packages.  With all
attempts to access said library (apart from an explicit `find-file'
maybe) resulting in either the core lisp version if exists or error.

That's why I say `package-suppress' is broken.  In a fresh -vanilla
21.5... 

(locate-library "regexp-opt")
 => "/usr/local/lib/xemacs/xemacs-packages/lisp/xemacs-base/regexp-opt.elc"

And `find-library', `find-function', `load', `require' all seem to use
the regexp-opt.elc from packages.

How do I do that?

I'd expect to see everything that returns an elisp library to never
return a suppressed one.  I'd expect to see everything that loads an
elisp library to never load a suppressed one.

Definitely.

That sounds like crazy talk to me. :-)

I'd really like to hear what Ben has to say, seeing as though he was
the one who wrote the suppression stuff.
