      Description

        On benchmarks with a large number of reference changes (like nosql benchmarks) on "large" machines we noticed that the HotCardCache_lock is highly contended(*).

        Investigate and fix this in the hope to improve behavior.

        (*) Contended as in at the time of trying to get ownership of the lock, there is already another owner of that lock.
