23326	DatabaseCache must implement incr to guarantee atomic increment	Vinay Anantharaman		django.core.cache.backends.db.DatabaseCache uses BasesCache's incr which does a get followed by a set. If the application uses multiple servers the increments will get clobbered. Furthermore, the current implementation overwrites the expiry time of a key to the default value instead of using the value which was initially set.
