Calling MultiCache.clear() doesn't run the finalizers in the subcaches

[vdvman1]

The MultiCache.clear() method just deletes the folder and its content, and never calls the clear method of the individual caches within it, leading to the finalizers never being run

Last time I checked it does run the finalizers though. The method also calls super().clear(), which invokes the implementation provided by python's MutableMapping abstract base class, which calls __delitem__ for each cache entry. The MultiCache calls the Cache.delete() method when caches are removed with __delitem__ so finalizers should run fine.

What about lazily loaded caches that haven't yet been loaded?

Ooh yeah you're right, I guess this could be fixed by calling self.preload() before doing anything in MultiCache.clear().
