This will probably not happen for a while -- my work on other aspects, 
and just staying on top of bugs and testing takes most of the available 
time.

But I think I can provide pieces of a recipe for this kind of debugging 
and if someone out there could give feedback, I will see to it that the 
recipe gets into the manual.

I think if you want to see the plan that ASDF produces to perform a 
requested operation, you should use something like:
```
(setf *plan* (asdf/plan:make-plan nil (make-operation 'load-op) 
(find-system "sysname")))
```

Then, to figure out what's happening, I would suggest
```
(trace asdf:operation-done-p)
```
...to see if ASDF is wrong about whether or not it needs to do some 
operations.

Then I would try something like tracing `PERFORM`.

I'd have to think a little about what to do if `MAKE-PLAN` gives you a 
plan you don't expect.
