Public bug reported:

`Axiom._fincache`, the code in `Store` that uses it, and the relevant
tests rely on objects being deallocated and weakref finalizers being
called at very specific times. On PyPy, these events do not occur at
quite the same times that the code expects, resulting in errors. I
believe it is possible to cope with this by adjusting the way the code
uses the cache; while items may still linger in the cache for longer
than they would have on CPython, I do not think this should cause any
application-level breakage except in application code that is doing
extremely unsupported things.
