There's probably a better way, but when I wrote dvc-reload, I didn't
find a way to unload a feature and its dependancies at the same time
(I don't remember the exact reason which made the FORCE argument
insuficient, but IIRC there was one).

At that time, we had 5 to 10 source files, so it was completely
reasonable to have a hardcoded list, but it would make sense to have
something better now.

Be carefull to write portable code (XEmacs and Emacs 21 in
particular).

Indeed, I think it's possible to write a 'unload-feature-recursive'
completely genericly and dynamically (by replacing the error by a
recursive call in unload-feature).
