The before and after methods on stroke for char-boxes both use a kind of
run-time switch. Nevertheless, they are slowing down things considerably.

The only solution I can imagine is setting :no-typeset-decoration at
compile-time. It should be established only for the applications that do
need decoration. The net problem, separating binaries, i.e. fasl-files, is
easily solved with LispWorks defsystem but, AFAIK, is hardly treatable by
means of ASDF.
