I'm not entirely sure what you intend this to be used for.

Do you want normal pieces of application code unloaded?

Do you want large blobs of static data to be unloaded? In which case 
don't you want more fine control over that?

Do you want small pieces of generated code to be unloaded? Perhaps 
individual class loaders are more appropriate.
