It may also be a bug in my understanding of how asdf should be used.

I agree. Wholeheartedly. :-)

Create file1.lisp and file2.lisp, and then

(asdf:defsystem test
  :components ((:file "file1")
               (:file "file2" :depends-on ("file1"))))

(asdf:oos 'asdf:load-op 'test1)

;; file1.lisp and file2.lisp are now compiled and loaded. Everything's
;; fine so far. 

(let* ((name1 (compile-file-pathname "file1"))
       (date1 (file-write-date name1))
       (name2 (compile-file-pathname "file2"))
       (date2 (file-write-date name2)))
  (sleep 2) 
  (asdf::run-shell-command "touch file1.lisp")
  (asdf:oos 'asdf:load-op 'test1)
  (values (< date1 (file-write-date name1)) (< date2 (file-write-date name2))))


--> T,NIL

instead of T,T. That is, file1.lisp is recompiled but file2.lisp is
not.
