18482	Cache backend API should close()	Russell Keith-Magee	nobody	"At present, only the memcached cache backends have a close() method. This means that you can't reliably call close() on a cache -- you need to protect it with ""hasattr(cache, 'close')"". 

Django's own code even does this, in the end-request signal handler.

The cache backend API should include a no-op close() method by default, matching the API from the memcached backend.

The close() method (and the end-request handler) were added in r8418
