If there's something wrong with BackgroundRB and sweepers, have you
tried:
In the BackgroundRB worker:
my_model = MyModel.create(blah blah blah)
my_model.clear_the_cache
and inside MyModel
def clear_the_cache
Rails.cache.clear(cache_path from data)
end
AR.create *should* be handing back a model, which could self-inspect to
derive the cache path to expire...
