Dmitry Tantsur 8d52482c79 Make memoize behave better in concurrent environments ... Currently there is a chance for System view to raise sqlite3 exceptions because of table lock in PersistentDict. 1) Stop re-loading content on PersistentDict creation. 2) Retry OperationalError on all database accesses. 3) Rule out a race condition in __delitem__ Also refactor tests to remove excessive mocking.
