15337	cyclic import dependency when extend builtin backend	yi.codeplayer@…	nobody	"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.
