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.
