:reread-system-defs

Occasionally I find that I want to force asdf to reread system  
definitions. This may happen because I forget to push a feature or  
because I've downloaded an update. AFAIK, the only way to do this is  
by evaluating (clrhash asdf::*defined-systems). What do people think  
about adding :reread-system-defs to operate?

The patch looks like

> (defgeneric traverse (operation component))
> (defmethod traverse ((operation operation) (c component))
>   (%traverse operation c))
>
> (defmethod traverse :around ((operation operation) (c system))
>   (let* ((args (copy-list (operation-original-initargs operation))))
>     (when (getf args :reread-system-defs)
>       (print "Reread system defs")
>       (clrhash *defined-systems*))
>     (call-next-method)))
>
> (defgeneric %traverse (operation component))
> (defmethod %traverse ((operation operation) (c component))

<snip -- the rest of the current traverse method>

thoughts? opinions? flames?

thanks,
