> The {{DefaultSessionProvider}} used by the {{QueryReplayer}} caches the
> sessions by hostname. When closing, the sessions and their associated
> clusters are closed but they never get removed from the cache.
> When connecting to the same host, the closed session is returned, which is
> unexpected.
> Besides the unexpected behavior, the session references remaining in the
> cache leaks resources.
