(self, key, file)
Implementation of :meth:`~simplekv.KeyValueStore.get_file`.

        If a cache miss occurs, the value is retrieved, stored in the cache and
        returned.

        If the cache raises an :exc:`~exceptions.IOError`, the retrieval cannot
        proceed: If ``file`` was an open file, data maybe been written to it
        already. The :exc:`~exceptions.IOError` bubbles up.

        It is possible for a caching error to occur while attempting to store
        the value in the cache. It will not be handled as well.
