Actually, the more I look at this, the more odd it seems.

We don't simply use the cache if IN-FILESYSTEM is NIL -- we do it only
if IN-FILESYSTEM is NIL and *ASDF-CACHE* is bound (and we check the
latter first).

Can't we just branch on IN-FILESYSTEM, and error out if (NOT
IN-FILESYSTEM) and *ASDF-CACHE* is NIL?  In that case, the programmer
has said: "I want to use the cache," and we are quietly ignoring the
request and using the filesystem.  I'd rather we blow up when we flout
the programmer's directive, instead of trying to DWIM it in a weird way.

Is that an acceptable mod?  I'm going to push a candidate patch.
