        Returns a synchronized type-specific big list backed by the given type-specific big list, using an assigned object to synchronize.
        Parameters:
        l - the big list to be wrapped in a synchronized big list.
        sync - an object that will be used to synchronize the access to the big list.
        Returns:
        a synchronized view of the specified big list.
