There would be several benefits if FIND-SYSTEM were to simply PROBE-FILE for a system definition in each of the configured paths (e.g. path1/system.asd, path2/system.asd) until one is found. Better efficiency, no pollution from unrelated packages, etc.

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.
