I still don't get it. I'm looking at asdf.lisp, and it's basically
doing what you say:
1. call system-definition-pathname to find the system definition file.
2. if there's a previously-loaded system definition, check to see if
it's stale. If so, reload.
3. If there's no previously-loaded system definition, load
4. return the system definition.
In stock (upstream) asdf, there's no loading in
sysdef-central-registry-search, so I still don't see what's going wrong
here. Is this SBCL-specific?
As for the fact that people can put code like
(asdf:oos 'asdf:load-op <system I need at read time>)
in their .asd files, that seems to me to be a feature, not a bug.
