Can getValue use RLock?

c.mu.Lock()

can here use RLock to decrease lock race?

sort of...getValue() checks if the item has expired, and deletes it if it has. So you'd have to convert the reader lock to a full lock.

Also the cache engine supports a loaderFunc that will attempt to generate a value if it's not found in the cache. That would also require a real Lock.
