Description

When writing a custom cache backend which inherit from django's builtin memcache backend, say mycache.py: 

    from django.core.cache.backends.memcached import CacheClass as BaseCacheClass
    class MyCache(BaseCacheClass):
        ....

and set backend to "mycache.MyCache" in settings.py, then mycache.py and django.core.cache.init.py import each other.
Turn django.core.cache.init.py::cache object to be a SimpleLazyObject would solve this problem.
