It's a consequence of the use the "value cache," which allows responses from the data server to be made visible to waiting client threads without initiating a new transaction to insert the responses (which would force all waiting transactions to roll back).

The bug arises when:

A lock is released, but its value is not removed from mem store; the lock is re-obtained, its value added to cache, but the mem store is consulted before the cache.
