18541	Infinite Lock With Caching Backend	zmsmith	nobody	"Basically, if you try to cache an object with a {{{__getstate__}}} method that hits the cache, the LocMem backend will enter an infinite lock.

I discovered this when a QuerySet that was using a caching manager was being written to the cache and pickling forced the QuerySet to evaluate and interact with the cache.

The test I added covers this scenario, but unfortunately the failure condition is an infinite lock that will just hang and give no feedback about the failing test. I didn't know if django has any convention for timing out tests, so I didn't try to create one."	Bug	closed	Core (Cache system)	1.4	Normal	duplicate	caching		Accepted	1	1	0	1	0	0
